Core Pillars
Four core pillars: Mnemonic, Discoverability, Consistency, "Crowd-Configured".
If any of these core pillars is violated open an issue and we'll fix it.
Mnemonic
Spacemacs
organizes key bindings by mnemonic namespaces as much as possible.
If you are looking for commands to operate on your buffer, they are right under
SPC b, if you want to operate on your project, then it is
SPC p, etc...
Discoverability
Spacemacs
comes with a dedicated major mode spacemacs-mode
. Its goal is to
give useful feedbacks and easily perform maintenance tasks.
It also comes with dedicated [helm][] sources to quickly find layers, packages and more.
guide-key is enabled by default, it will display all the available key bindings in a dedicated popup buffer.
Consistency
Similar functionalities should have the same key binding no matter which major
is currently active. For instance if you are looking for the definition of a
function, the binding is SPC m g g, m
for major mode
and g g
for go to thing at point
. No matter what is the major mode it is the same
binding to perform this action.
This is also true for the documentation, each configuration layer comes with
an associated README.md
file with the same base layout.
The consistency core pillar is supported by a convention file: CONVENTIONS.md
Crowd-Configured
By defining an very light structure called configuration layer
which is easy
to understand, Spacemacs
makes it easy to contribute additional support.
The conventions in CONVENTIONS.md make it easy to get the spacemacs way and keep consistency even if there are a lot of contributions.
Crowd-configuration
is the most powerful pillar of Spacemacs
. Anybody can
submit upstream improvements to configuration layers or a whole new one. Any
user can easily and directly use this layer by adding it to a list in a
dotfile. It is even possible to exclude any unwanted packages.
Goals
-
Bring the power of modal editing to the powerful Emacs editing platform.
-
Integrate nicely with
Evil
states (Vim
modes):Spacemacs
tries to keep your fingers on the home row as much as possible, no matter the mode you are in. -
Crowed-configured: Contribute easily your improvements and new configuration layers.
-
Minimalistic and nice graphical UI, keep your available screen space for what matters: your text files.
-
Mnemonic and consistent key bindings which should be easier to learn and remember and be the same in all major modes.
-
Fast boot time, everything is lazy-loaded.
-
Lower the risk of RSI by heavily using the space bar instead of modifiers.
-
Hopefully, if it's not already the case:
Ɛ>Ɛ>Ɛ> make you love modal editing! <3<3<3
Screenshots
Note: Even though screenshots are updated frequently, Spacemacs
is evolving
quickly and the screenshots may not reflect exactly the current state of the
project.
Who can benefit from this ?
Spacemacs
is first intended to be used by Vim users who want to go to the
next level by using Emacs.
It is also a good fit for people wanting to lower the risk of RSI induced by the default Emacs key bindings (this is an assumption, there is no official studies to prove this).
Emacs users wanting to learn a different way to edit files or wanting to learn Vim key bindings.
As a side note, if you are a programmer and you don't know Vim key bindings yet, I deeply recommend you to learn the basics as recommended in Sacha Chua's one-page guide about how to learn Emacs.
Update and Rollback
For now it is still needed to update the Spacemacs
repository manually.
Update Spacemacs repository
Close Emacs and update the git repository:
git pull --rebase
git submodule sync; git submodule update
Note It is recommended to update the packages first, see next session.
Update packages
To update Spacemacs
press RET (enter) or click on the link
[Update]
in the startup page under the banner then restart Emacs.
If anything goes wrong you should be able to rollback the update by pressing
RET or clicking on the [Rollback]
link next to the [Update]
link and choose a rollback slot (sorted by date).
Configuration layers
Structure
Configuration is organized in layers. Each layer has the following structure:
[layer_name]
|__ [extensions]
| |__ [mode 1]
| | ...
| |__ [mode n]
|__ config.el
|__ extensions.el
|__ funcs.el
|__ keybindings.el
|__ packages.el
[] = directory
Where:
File | Usage
------------------|----------------------------------------------------------- config.el | Emacs built-in configuration or mandatory configuration extensions.el | The list of extensions to load and the functions to initialize them funcs.el | Various functions and macros (often used in keybindings.el) keybindings.el | Emacs built-in key bindings or mandatory key bindings packages.el | The list of packages to install and the functions to initialize them
Packages
are ELPA
packages which can be installed from an ELPA
compliant
repository, and Extensions
are generally elisp code from git submodules.
Extensions and Packages
Declaration
Extensions
and Packages
are declared in variables <layer>-pre-extensions
,
<layer>-post-extensions
and <layer>-packages
where <layer>
is the layer
name. Pre-Extensions
are loaded before Packages
and Post-Extensions
are
loaded after Packages
.
They are processed in alphabetical order so sometimes you'll have to use
some eval-after-load
black magic.
Example:
(defvar <layer>-packages
'(
package1
package2
)
Initialization
To initialize an extension or a package xxx
, define a function with this
format in extensions.el
or packages.el
:
(defun <layer>/init-xxx ()
...body
)
It is common to define the body with the use-package macro.
Exclusion
It is possible to exclude some packages from Spacemacs
in a per layer basis.
This is useful when a configuration layer aims to replace a stock package
declared in the Spacemacs
layer.
To do so add the package names to exclude to the variable
<layer>-excluded-packages
.
Example:
(defvar <layer>-excluded-packages
'(
package1
)
Packages synchronization (Vundle like feature)
Spacemacs
features a synchronization engine for the ELPA packages. It means
that Spacemacs
will auto-install the new packages in <layer>-packages
lists
and auto-delete orphan packages in your elpa
directory.
It effectively makes Spacemacs
behave like Vundle.
Types of configuration layers
There are three types of configuration layers:
- core (this is the
Spacemacs
layer) - private (in the
private
directory, they are ignored by Git) - contrib (in the
contrib
directory, those layers are contributions shared by the community and merged upstream).
Submitting a configuration layer upstream
If you decide to provide a contrib
configuration layer, please check
the contribution guidelines in CONTRIBUTE.md.
Example: Themes Megapack example
This is a simple contrib
configuration layer listing a bunch of themes,
you can find it here.
To install it, just add themes-megapack
to your ~/.spacemacs
like so:
dotspacemacs-configuration-layers '(themes-megapack)
You have now installed around 100 themes you are free to try with SPC T h (helm-themes).
Managing private configuration layers
Spacemacs
configuration system is flexible enough to let you manage your
private layers in different ways.
Using the private directory
Everything in the private directory is ignored by Git so it is a good place to store private layers. There is a huge drawback to this approach though: your layers are not source controlled.
Using an external Git repository
This is the recommended way to manage your private layers.
The best approach is to store all your private layers into an external Git
repository. It is especially a good practice to store them in your dotfiles
repository if you have one. Put also your ~/.spacemacs
file in it.
Then you are free to symlink your layers into ~/emacs.d/private
or let
them anywhere you want and reference the parent directory in the variable
dotspacemacs-configuration-layer-path
of your ~/.spacemacs
.
Note that you could also have a dedicated repository for all your private
layers and then directly clone this repository in ~/.emacs.d/private
.
Using a personal branch
The final main way to manage your private layers is to push them in a personal
branch that you keep up to date with upstream master
or develop
.
Dotfile Configuration
User configuration can be stored in your ~/.spacemacs
file.
Installation
~/.spacemacs
is an optional file. If you want to use it you have to copy it
manually from the template file ~/.emacs.d/core/templates/.spacemacs.template
$ cp ~/.emacs.d/core/templates/.spacemacs.template ~/.spacemacs
Content
Using configuration layers
To use a configuration layer, add it to the dotspacemacs-configuration-layers
variable of your ~/.spacemacs
.
For instance to add the configuration layer of RMS:
(setq-default dotspacemacs-configuration-layers '(rms))
If this layer does not exist you can still try another one in
the contrib
directory.
Configuration layers are expected to be stored in ~/.emacs.d/private
or
~/.emacs.d/contrib
. But you are free to keep them somewhere else by declaring
additional paths where Spacemacs
can look for configuration layers.
This is done by setting the list
dotspacemacs-configuration-layer-path
in your ~/.spacemacs
:
(setq-default dotspacemacs-configuration-layer-path '("~/.myconfig/"))
Setting configuration layers variables
Some configuration layers have configuration variables to enable specific
support. For instance the git layer has several configuration variables,
they can be set directly in the dotspacemacs-configuration-layers
like this:
;; List of configuration layers to load.
dotspacemacs-configuration-layers '(company-mode
(git :variables
git-magit-status-fullscreen t
git-enable-github-support t
git-gutter-use-fringe t)
smex)
Excluding packages
You can exclude packages you don't want to install with the variable
dotspacemacs-excluded-packages
, this variable can exclude both packages and
extensions (see Configuration layers for more info
on packages and extensions).
For instance to disable the rainbow-delimiters
package:
(setq-default dotspacemacs-excluded-packages '(rainbow-delimiters))
When you exclude a package, Spacemacs
will automatically delete it for you
the next time you launch Emacs. All the orphan dependencies are as well
delete automatically.
Hooks
Two special functions of the ~/.spacemacs
file can be used to perform
configuration at the beginning and end of Spacemacs
loading process.
dotspacemacs/init
is triggered at the very beginning ofSpacemacs
loading.dotspacemacs/config
is triggered at the very end ofSpacemacs
loading.
Custom variables
Custom variables configuration from M-x customize-group
which are
automatically saved by Emacs are stored at the end of your ~/.spacemacs
file.
Main principles
Evil
Spacemacs
uses the evil mode to emulate Vim key bindings. It is a
very complete emulation, maybe the most advanced. In fact, Evil is much more
than just a Vim emulation. It has more states than Vim for instance.
States
Spacemacs
has 8 states:
- Normal (orange) - like the
normal mode of Vim
, used to execute and combine commands - Insert (green) - like the
insert mode of Vim
, used to actually insert text - Visual (gray) - like the
visual mode of Vim
, used to make text selection - Motion (purple) - exclusive to
Evil
, used to navigate read only buffers - Emacs (blue) - exclusive to
Evil
, using this state is like using a regular Emacs without Vim - Lisp (pink) - exclusive to
Spacemacs
, used to navigate Lisp code and modify it (see Editing Lisp code) - Iedit (red) - exclusive to
Spacemacs
, used to navigate between multiple regions of text usingiedit
(see Replacing text with iedit) - Iedit Insert (red) - exclusive to
Spacemacs
, used to replace multiple regions of text usingiedit
(see Replacing text with iedit)
Note: Technically speaking there are also the operator
and replace
evil
states.
Evil leader
Spacemacs
heavily uses the evil-leader mode which brings the
Vim leader key to the Emacs world.
This leader key is commonly set to ,
by Vim users, in Spacemacs
the leader
key is set on SPC (space bar, this is why the name spacemacs
).
This key is the most accessible key on a keyboard and it is pressed with the
thumb which is a good choice to lower the risk of RSI.
So with Spacemacs
there is no need to remap your keyboard modifiers to
attempt to reduce the risk of RSI, every command can be executed very easily
while you are in normal
mode by pressing the SPC leader key,
here are a few examples:
- Save a buffer: SPC f s
- Save all opened buffers: SPC f S
- Open (switch) to a buffer with
helm
: SPC b s
Universal argument
The universal argument C-u
is an important command in Emacs but it is also
a very handy Vim key binding to scroll up.
Spacemacs
binds C-u to scroll-up
and change the universal
argument binding to SPC u.
Micro-states
Spacemacs
defines a wide variety of micro-states
(temporary overlay maps)
where it makes sense. This prevents one from doing repetitive and tedious presses on the
SPC key.
When a micro-state
is active, a documentation is displayed in the minibuffer.
Additional information may as well be displayed in the minibuffer.
Auto-highlight-symbol micro-state:
Differences between Vim, Evil and Spacemacs
No doubt that Evil
is one of the most advanced Vim
emulation and you should
not see big difference between Vim
and Emacs
. I did not find any command I
used in Vim that I missed in Emacs with Evil
.
Send a PR to add the differences you found in this section.
The vim-surround case
There is one obvious visible difference though. It is not between Evil
and
Vim
but between Spacemacs
and vim-surround: the surround
command is
on S in vim-surround
whereas it is on s in Spacemacs
.
This is something that can surprise some Vim users so let me explain why this is the case:
s
andc
do the same thing invisual state
,s
is only useful to delete one character and add more than one character which is a very narrow use case,c
accept motions and can do everythings
can do innormal state
,- this is also true for
r
butr
is more useful because it stays innormal state
. surround
command is just a more powerful command thans
If you are not convinced, then here is the snippet to revert back to the default
Vim + vim-surround
setup (add it to your dotspacemacs/config
function or
your ~/.spacemacs
):
(evil-define-key 'visual evil-surround-mode-map "s" 'evil-substitute)
(evil-define-key 'visual evil-surround-mode-map "S" 'evil-surround-region)
Evil plugins
Spacemacs
ships with the following evil plugins:
Mode | Description
----------------------------------------|--------------------------------------
evil-leader | vim leader that bring a new layer of keys in normal mode
evil-indent-textobject | add text object based on indentation level
evil-visualstar | search for current selection with *
evil-exchange | port of vim-exchange
evil-surround | port of vim-surround
evil-matchit | port of matchit.vim
evil-nerd-commenter | port of nerdcommenter
[evil-search-highlight-persist][] | emulation of hlsearch behavior
evil-numbers | like C-a/C-x in vim
evil-args | motions and text objects for arguments
evil-jumper | jump list emulation
NeoTree | mimic NERD Tree
Spacemacs UI
Spacemacs
has unique UI elements to make the Emacs experience even
more enjoyable:
- dedicated startup page with a mode aimed at easily managing
Spacemacs
- dedicated helm source via
helm-spacemacs
- a guide-key buffer
Graphical UI
Spacemacs
has a minimalistic and distraction free graphical UI:
- custom powerline mode-line with color feedback according to current Flycheck status
- unicode symbols for minor mode lighters which appear in the mode-line
- custom fringe bitmaps and error feedbacks for Flycheck
- custom fringe bitmaps for git gutter (available in git layer)
Color themes
By default, Spacemacs
uses the theme solarized-light.
It is possible to define your default themes in your ~/.spacemacs
with
the variable dotspacemacs-themes
. For instance, to specify leuven
and
zenburn
(high contrast theme and low contrast theme):
(setq-default dotspacemacs-themes '(leuven zenburn))
Key Binding | Description
---------------------|------------------------------------------------------------
SPC T n | switch to next theme listed in dotspacemacs-themes
.
SPC T h | select a theme using a helm
buffer.
Note: Due to the inner working of themes in Emacs, switching theme during the same session may have some weird side effects. Although these side effects should be pretty rare.
Hint If you are an Org
user, leuven-theme is amazing ;-)
Font
The default font used by Spacemacs
is source code pro by Adobe. It is
recommended to install it on your system.
To change the default font set the variable dotspacemacs-default-font
in
your .spacemacs
file.
By default its value is:
(setq-default dotspacemacs-default-font '("Source Code Pro"
:size 13
:weight normal
:width normal
:powerline-scale 1.1))
The properties should be pretty straightforward, it is possible to set any valid property of a font-spec:
:family
Font family or fontset (a string).:width
Relative character width. This should be one of the symbols:- ultra-condensed
- extra-condensed
- condensed
- semi-condensed
- normal
- semi-expanded
- expanded
- extra-expanded
- ultra-expanded
:height
The height of the font. In the simplest case, this is an integer in units of 1/10 point.:weight
Font weight—one of the symbols (from densest to faintest):- ultra-bold
- extra-bold
- bold
- semi-bold
- normal
- semi-light
- light
- extra-light
- ultra-light
:slant
Font slant—one of the symbols:- italic
- oblique
- normal
- reverse-italic
- reverse-oblique
:size
The font size—either a non-negative integer that specifies the pixel size, or a floating-point number that specifies the point size.:adstyle
Additional typographic style information for the font, such as ‘sans’. The value should be a string or a symbol.:registry
The charset registry and encoding of the font, such as ‘iso8859-1’. The value should be a string or a symbol.:script
The script that the font must support (a symbol).
The special property :powerline-scale
is Spacemacs
specific and it is for
quick tweaking of the mode-line height in order to avoid crappy rendering of
the separators like on the following screenshot (default value is 1.1).
Ugly separators
Graphical UI Toggles
Some graphical UI indicators can be toggled on and off (toggles start with t
):
Key Binding | Description
----------------------|------------------------------------------------------------ SPC t 8 | display a mark on the 80th column SPC t F | toggle frame fullscreen SPC t f | toggle display of the fringe SPC t h | toggle highlight of the current line SPC t i | toggle aggressive indent SPC t l | toggle truncate lines SPC t L | toggle visual lines SPC t M | toggle frame maximize SPC t n | show the absolute line numbers SPC t t | toggle frame transparency SPC t T | toggle tool bar SPC t U | toggle menu bar
Note These toggles are all available via the helm-spacemacs
interface
(press SPC fe h to display the helm-spacemacs
buffer).
Mode-line
The mode line is a heavily customized powerline with the following capabilities:
- show the window number
- color code for current state
- show the number of search occurrences via anzu
- toggle flycheck info
- toggle battery info
- toggle minor mode lighters
Reminder of the color codes for the states:
Evil State | Color |
---|---|
Normal | Orange |
Insert | Green |
Visual | Grey |
Emacs | Blue |
Motion | Purple |
Lisp | Pink |
Iedit/Iedit-Insert | Red |
Some elements can be dynamically toggled:
Key Binding | Description
-----------------------|------------------------------------------------------------ SPC t m m | toggle the minor mode lighters SPC t m b | toggle the battery status SPC t m f | toggle the flycheck info SPC t m v | toggle the new version lighter
Flycheck integration
When Flycheck minor mode is enabled, a new element appears showing the number of errors, warnings and info.
Anzu integration
Anzu shows the number of occurrence when performing a search. Spacemacs
integrates nicely the Anzu status by displaying it temporarily when n
or N
are
being pressed. See the 5/6
segment on the screenshot below.
Battery status integration
fancy-battery displays the percentage of total charge of the battery as well as the time remaining to charge or discharge completely the battery.
A color code is used for the battery status:
Battery State | Color |
---|---|
Charging | Green |
Discharging | Orange |
Critical | Red |
Note the these colors may vary depending on your theme.
Powerline separators
It is possible to easily customize the powerline separator
by setting the
powerline-default-separator
variable in your ~./spacemacs
. For instance
if you want to set back the separator to the well-known arrow
separator
add the following snippet to your configuration file:
(defun dotspacemacs/config ()
"This is were you can ultimately override default Spacemacs configuration.
This function is called at the very end of Spacemacs initialization."
(setq powerline-default-separator 'arrow)
)
To save you the time to try all the possible separators provided by the powerline, here is an exhaustive set of screenshots:
Separator | Screenshot
------------------|------------------------------------------------------------
alternate
|
arrow
|
arrow-fade
|
bar
|
box
|
brace
|
butt
|
chamfer
|
contour
|
curve
|
rounded
|
roundstub
|
slant

wave
|
zigzag

Minor Modes
Spacemacs
uses diminish mode to reduce the size of minor mode
indicators:
The minor mode area can be toggled on and off with:
<SPC> t m m
Unicode symbols are displayed by default. Setting the variable
dotspacemacs-mode-line-unicode-symbols
to nil
in your ~/.spacemacs
will
display ASCII characters instead (may be useful in terminal).
Unicode | ASCII | Mode |
---|---|---|
⊞ |
G | golden-ratio mode |
Ⓐ |
A | auto-complete mode |
Ⓒ |
C | centered-cursor mode |

Commands
Vim key bindings
Spacemacs
is based on Vim
modal user interface to navigate and edit text.
If you are not familiar with the Vim
way of editing text you can try the
[evil tutor][] lessons by pressing SPC h T at any time.
Escaping
Spacemacs
uses evil-escape to easily switch between insert state
and
normal state
by quickly pressing the fd
keys.
The choice of fd
was made to be able to use the same sequence to escape from
"everything" in Emacs:
- escape from all evil states to normal state
- escape from evil-lisp-state to normal state
- abort evil ex command
- quit minibuffer
- abort isearch
- quit magit buffers
- quit help buffers
- quit apropos buffers
- quit ert buffers
- quit undo-tree buffer
- quit paradox
- quit gist-list menu
- hide neotree buffer
This sequence can be customized in your ~/.spacemacs
. Example to set it
to jj
(it is important set the variable in dotspacemacs/init
):
(defun dotspacemacs/init ()
(setq-default evil-escape-key-sequence "jj"))
Note: Although jj
or jk
are popular choices of vim users, these key
sequences are not optimal for Spacemacs
. Indeed it is very easy in
visual state
to press quickly jj
and inadvertently escape to normal state
.
Executing Vim and Emacs ex/M-x commands
Command | Key Binding
:---------------:|------------------------------------------------------------------
Vim (ex-command) | :
Emacs (M-x) | SPC :
The command key :
can be easily changed with the variable
dotspacemacs-command-key
of your ~/.spacemacs
. Note that is will change both
:
and SPC :
bindings to keep the symmetry between Vim and Emacs. A good
key can be ,
for example.
Leader key
On top of Vim
modes (modes are called states in Spacemacs
) there is a
special key called the leader key which once pressed gives a whole new
keyboard layer. The leader key is by default SPC (space).
It is possible to change this key with the variable dotspacemacs-leader-key
.
Reserved prefix command for user
SPC o is reserved for the user. Setting key bindings behind
<SPC> o
is guaranteed to never conflict with Spacemacs
defaults key
bindings.
Helm
Spacemacs
is powered by Helm which is an incremental completion
and selection narrowing framework.
Helm
is the central control tower of Spacemacs
, it is used to manage
buffers, projects, search results, configuration layers, toggles and more...
Mastering Helm
will make you a Spacemacs
power user. Do not hesitate
to read the Helm documentation wiki.
Helm micro-state
Spacemacs
defines a micro-state for Helm
to make it
work like Vim's Unit plugin.
Initiate the micro-state with C-SPC while in a Helm
buffer.
Use C-SPC again to exit from the micro-state.
Key Binding | Description |
---|---|
C-SPC | initiate or leave the micro-state |
TAB | switch to actions page and leave the micro-state |
1 | execute action 0 |
2 | execute action 1 |
3 | execute action 2 |
4 | execute action 3 |
5 | execute action 4 |
6 | execute action 5 |
7 | execute action 6 |
8 | execute action 7 |
9 | execute action 8 |
0 | execute action 9 |
a | switch to actions page |
g | go to first candidate |
G | go to last candidate |
h | go to previous source |
j | select next candidate |
k | select previous candidate |
l | go to next source |
t | mark current candidate |
T | mark all candidates |
v | execute persistent action |
Discovering
Key bindings
An help buffer is displayed each time the SPC key is pressed in normal mode. It lists the available key bindings and their associated commands.
By default the guide-key buffer will be displayed quickly after the key
has been pressed. You can change the delay by setting the variable
dotspacemacs-guide-key-delay
to your liking (the value is in second).
Available layers
All layers can be easily discovered via helm-spacemacs
accessible with
SPC f e h.
The following helm actions are available:
- default: open the layer
README.md
- 2nd: open the layer
packages.el
- 3nd: open the layer
extensions.el
Available packages in Spacemacs
helm-spacemacs
also lists all the packages available in Spacemacs
.
The entry format is (layer) packages
. If you type flycheck
you'll
be able to see all the layers where flycheck
is used.
The following helm actions are available on packages:
- default: go the package init function
New packages from ELPA repositories
package-list-packages
is where you can browse for all available packages
in the different Elpa repositories. It is possible to upgrade packages
from there but it is not recommended, use the [Update]
link on the
Spacemacs
startup page instead.
Spacemacs
proposes to use Paradox instead of package-list-packages
to list available ELPA packages.
Paradox enhances the package list buffer with better feedbacks, new
filters and Github information like the number of stars. Optionally you
can also star packages directly in the buffer.
Important Note 1 Installing a new package from Paradox
won't make it
persistent. To install a package persistently you have to add it explicitly
to a configuration layer.
Important Note 2 Don't update your packages from Paradox
or
package-list-packages
because they don't support the rollback feature of
Spacemacs.
Key Binding | Description
---------------------|------------------------------------------------------------
/ | evil-search
f k | filter by keywords
f r | filter by regexp
f u | display only installed package with updates available
h | go left
H | show help (not accurate)
j | go down
k | go up
l | go right
L | show last commits
n | next search occurrence
N | previous search occurrence
o | open package homepage
r | refresh
S P | sort by package name
S S | sort by status (installed, available, etc...)
S * | sort by Github stars
v | visual state
V | visual-line state
x | execute (action flags)
Toggles
helm-spacemacs
is also a central place to discover the available toggles.
To display only the toggles source press C-l (or in
Helm micro-state you can press just l).
The following helm actions are available on packages:
- default: toggle on/off
Tips Use SPC h l to resume the last helm session. It is handy to quickly toggle on and off a toggle.
Navigating
Point/Cursor
Navigation is performed using the Vi key bindings hjkl
.
Key Binding | Description |
---|---|
h |
move cursor left |
j |
move cursor down |
k |
move cursor up |
l |
move cursor right |
H |
move quickly up (10 lines at a time) |
L |
move quickly down (10 lines at a time) |
SPC j h | go to the beginning of line (and set a mark at the previous location in the line) |
SPC j l | go to the end of line (and set a mark at the previous location in the line) |

variable in your ~/.spacemacs
to nil
:
(setq-default dotspacemacs-smooth-scrolling t)
Vim motions with ace-jump mode
Spacemacs

selected or not. By default golden-ratio
is off.
The mode can be toggled on and off with:
<SPC> t g
Buffers and Files
Spacemacs
uses ido
for opening files since ido
way to navigate
the file system is better than helm
in my opinion (especially because ido
can
remember the last selected directories and buffers, maybe helm can do this ?).
ido
is also used to kill buffers.

NeoTree file tree
Spacemacs
provides a quick and simple way to navigate in an unknown project
file tree with NeoTree.
To toggle the NeoTree
buffer press:
<SPC> f t
The NeoTree window always has the number 0
so it does not shift the current
number of the other windows. To select the NeoTree window you then use
SPC 0.
NeoTree navigation
Navigation is centered on the hjkl
with the hope to provide a fast navigation
experience like in [ranger][]:
Key Binding | Description |

l or RET | expand directory |
L | next sibling |
Note: The point is automatically set to the first letter of a node for a smoother experience.
Opening files with NeoTree
By default a file is opened in the last active window. It is possible to choose window number where to open a file by using a numeric argument, for instance 2 l or 2 RET will open the current file in the windows 2. It is also possible to open the file in a split window with | and -:
Key Binding | Description |
---|---|

Shells
Key bindings
Key Binding | Description |
---|---|
C-j | next item in history |
C-k | previous item in history |
SPC m h | browse history with helm (works in eshell and shell ) |
Staying in insert state
Navigating in shell buffers can be tricky because it is not possible to use the
leader in insert state
. Switching back and forth between normal and insert
states can be tedious. The solution to this is to use C-o then use
the leader key. C-o set the next key to be evaluated in
normal state
.
Bookmarks
Bookmarks can be set anywhere in a file. Bookmarks are persistent. They are very
useful to jump to/open a known project. Spacemacs
used helm-bookmarks
to
manage them.
Open an helm
window with the current bookmarks by pressing:
<SPC> h b
Then in the helm-bookmarks
buffer:
Key Binding | Description |
---|---|
CTRL+d | delete the selected bookmark |
CTRL+e | edit the selected bookmark |

SPC h r | restore saved highlights in the current buffer |
SPC h s | save current highlights |
Highlight current symbol
Spacemacs
supports highlighting of the current symbol on demand (provided by
the auto-highlight-symbol mode) and adds a micro-state to
easily navigate and rename this symbol.
It is also possible to change the range of the navigation on the fly to:
- buffer
- function
- visible area
To initiate the highlighting of the current symbol under point press SPC s h.
Navigation between the highlighted symbols can be done with the commands:
Key Binding | Description |
---|---|
* | initiate navigation micro-state on current symbol and jump forwards |
# | initiate navigation micro-state on current symbol and jump backwards |
SPC s b | go to the last searched occurrence of the last highlighted symbol |
SPC s e | edit all occurrences of the current symbol(*) |
SPC s h | highlight the current symbol and all its occurrence within the current range |
SPC s R | change range to default (whole buffer ) |
In 'Spacemacs' highlight symbol micro-state:
Key Binding | Description |
---|---|
e | edit occurrences (*) |
n | go to next occurrence |
N | go to previous occurrence |

D | go to previous definition occurrence |
r | change range (function , display area , whole buffer ) |
R | go to home occurrence (reset position to starting occurrence) |
Any other key | leave the navigation micro-state |
(*) using iedit or the default implementation of auto-highlight-symbol
The micro-state text in minibuffer display the following information:
<M> [6/11]* press (n/N) to navigate, (e) to edit, (r) to change range or (R) for reset
Where <M> [x/y]*
is:
- M: the current range mode
<B>
: whole buffer range<D>
: current display range<F>
: current function range
x
: the index of the current highlighted occurrencey
: the total number of occurrences*
: appears if there is at least one occurrence which is not currently visible.
Visual Star
With evil-visualstar you can search for the next occurrence of the current selection.
It is pretty useful combined with the expand-region bindings.
Note: If the current state is not the visual state
then pressing *
uses
auto-highlight-symbol and its micro-state.
Listing symbols by semantic
Use helm-semantic-or-imenu
command from Helm
to quickly navigate between
the symbols in a buffer.
To list all the symbols of a buffer press:
<SPC> s l
Helm-swoop
This is very similar to moccur
, it displays a helm
buffer with all the
occurrences of the word under point. You can then change the search query
in real-time and navigate between them easily.
You can even edit the occurrences directly in the helm
buffer and apply
the modifications to the buffer.
Key Binding | Description |
---|---|
SPC s s | execute helm-swoop |

Smartparens Strict mode
Smartparens comes with a strict mode which prevents deletion of parenthesis if the result is unbalanced.
This mode can be frustrating for novices, this is why it is not enabled by default.
It is possible to enable it easily for all programming modes with the
variable dotspacemacs-smartparens-strict-mode
of you ~/.spacemacs
.
(setq-default dotspacemacs-smartparens-strict-mode t)

- | decrease the font size |
= | reset the font size |
Any other key | leave the font scaling micro-state |
Note that only the text of the current buffer is scaled, the other buffers,
the mode-line and the minibuffer are not affected. To zoom the whole content of
a frame use the zoom frame
bindings (see next section).

Major Mode leader key
Key bindings specific to the current major mode
start with SPC m.
For convenience a shortcut key called the major mode leader key is set by
default on , which saves one precious keystroke.
It is possible to change the major mode leader key by defining the variable
dotspacemacs-major-mode-leader-key
in your ~/.spacemacs
. For example to
setup the key on tabulation:
(setq-default dotspacemacs-major-mode-leader-key "<tab>")

Emacs Server
Spacemacs
starts a server at launch. This server is killed whenever you close
your Emacs windows.
Connecting to the Emacs server
TODO
Keeping the server alive
It is possible to keep the server alive when you close Emacs by setting the
variable dotspacemacs-persistent-server
to t
in your ~./spacemacs
.
(setq-default dotspacemacs-persistent-server t)
When this variable is set to t
, the only way to quit Emacs and kill the
server is to use the following bindings:
Key Binding | Description
-------------------|------------------------------------------------------------ SPC q q | Quit Emacs and kill the server, prompt for changed buffers to save SPC q Q | Quit Emacs and kill the server, lose all unsaved changes. SPC q s | Save the buffers, quit Emacs and kill the server SPC q z | Kill the current frame
Troubleshoot
Loading fails
If during the first boot of Emacs nothing seems to happen or if the
installation seems to abort prematurely, you can check for an error message
by opening the *Warning*
buffer:
C-x b warning RET
('C-x b' means 'Ctrl + x then b' and 'RET' means 'return')
Then you can copy/paste the error in a Github issue, thank you.
I have no file ~/.spacemacs
You have to manually copy the ~/.emacs.d/core/templates/.spacemacs.template
file to ~/.spacemacs
Tips
evil-lisp-state as default state
To Make lisp state
the default state in Emacs Lisp
buffers, insert in
your ~/.spacemacs
the following snippet:
(defun dotspacemacs/config ()
(add-hook 'emacs-lisp-mode-hook 'evil-lisp-state))
