Use mnemonic j for jumping commands. Although some of these commands
exist in other places, they are duplicated here when they don't
conflict.
Add:
1. jb for bookmark-jump
2. jc for avy char jump
3. jd for dired-jump
4. jD for dired-jump-other-window
5. jf for find-function-at-point
6. ji for spacemacs/jump-in-buffer (imenu)
7. jI for helm imenu in all buffers
8. jl for avy go to line
9. ju for avy-pop-mark (u for "undo")
10. jU for spacmacs/avy-goto-url
11. jv for find-variable-at-point
12. jw for avy go to word or subword
Move:
1. jh to j0 (push mark and go to beginning of line)
1. jl to j$ (push mark and go to end of line)
The current way to highlight TODOs is `spacemacs/highlight-TODO-words`
which is a spacemacs' hard-coded function.
This commit changes it for the `hl-todo` package. This imply:
- More keywords are supported out of the box.
- Keywords are associated to faces, so they are shown in different
colors.
- Keywords are stored with their faces in a list, so it's easier for
users to add their own keywords and faces (as contrary to a regexp).
- It is possible to disable highlighting by simply excluding the
package.
I feel that it is not needed because it makes not a lot of sense to
have it non global since it is a dotfile variable.
Also remove ' from the docstring for consistency.
`global-linum-mode` is making line numbers appearing in `*spacemacs*`
and `helm` buffers, what is annoying.
This change make the linum `SPC t n` toggle buffer-local, and add a
customization variable in `.spacemacs` to enable line numbers globally.
«Globally» here as to be understood as «in `prog-mode` and `text-mode`».
