;;
;;; Commentary:
;;
;; Commands to zoom into and out of text. They zoom a frame or a
;; buffer, so that the text appears larger or smaller.
;;
;; Commands `zoom-in', `zoom-out', and `zoom-in/out' do both kinds of
;; zooming. They can behave like command `text-scale-adjust',
;; zooming a buffer wherever it is displayed, or they can zoom an
;; entire single frame (all of its windows). Hit `C-u' at any time
;; while using these commands to toggle between buffer and frame
;; zooming.
;;
;; Because it is a more general replacement for `text-scale-adjust',
;; I suggest you bind `zoom-in/out' to the keys bound by default to
;; `text-scale-adjust': `C-x C-+', `C-x C-=', `C-x C--', and `C-x
;; C-0'.
;;
;; It is also handy to use a mouse button or wheel for zooming, hence
;; the mouse binding suggestions. For example, binding `zoom-in' and
;; `zoom-out' to mouse wheel events gives you the zooming effect you
;; are perhaps used to in a Web browser.
;;
;; User option `zoom-frame/buffer' determines which kind of zooming
;; (frame or buffer) is used by default. You can customize this
;; option, but (in Emacs 23 or later) you can also toggle it just by
;; providing a prefix arg (`C-u') to `zoom-in/out', `zoom-in', or
;; `zoom-out'.
;;
;; Note about saving changes made dynamically using the commands
;; defined here:
;;
;; Some of the commands defined here change frame properties. You
;; can save any changes you have made, by using Customize. To
;; visit a Customize buffer of all unsaved changes you have made,
;; use command `customize-customized'.
;;
;; Frame parameter changes, such as font size, can be saved for
;; future use by all frames or all frames of a certain kind. For
;; that, you must change the frame parameters of the correponding
;; frame-alist variable.
;;
;; There is no single variable for saving changes to parameters of
;; the current frame. Instead, there are several different
;; frame-alist variables, which you can use to define different
;; kinds of frames. These include: `default-frame-alist',
;; `initial-frame-alist', and `special-display-frame-alist'. The
;; complete list of such frame alist variables is available using
;; function `frame-alist-var-names', defined in library
;; `frame-cmds.el'.
;;
;; Example: Suppose you change the font size of a frame and want to
;; make that the default font size for new frames in the future.
;; You will need to update the value of variable
;; `default-frame-alist' to use the `font' parameter setting of the
;; changed frame.
;;
;; You can easily copy one or all parameter values from any given
;; frame to any frame alist (such as `default-frame-alist'), by
;; using the commands `set-frame-alist-parameter-from-frame' and
;; `set-all-frame-alist-parameters-from-frame'. Those commands are
;; defined in library `frame-cmds.el'.
;;
;;
;; Commands defined here:
;;
;; `toggle-zoom-frame', `zoom-all-frames-in',
;; `zoom-all-frames-out', `zoom-frm-in', `zoom-frm-out',
;; `zoom-frm-unzoom', `zoom-in', `zoom-in/out' (Emacs 23+),
;; `zoom-out'.
;;
;;
;; User options (variables) defined here:
;;
;; `frame-zoom-font-difference', `zoom-frame/buffer' (Emacs 23+).
;;
;;
;; Put this in your init file (`~/.emacs'): (require 'zoom-frm)
;;
;; Suggested key bindings:
;;
;; Emacs 23 and later:
;;
;; (define-key ctl-x-map [(control ?+)] 'zoom-in/out)
;; (define-key ctl-x-map [(control ?-)] 'zoom-in/out)
;; (define-key ctl-x-map [(control ?=)] 'zoom-in/out)
;; (define-key ctl-x-map [(control ?0)] 'zoom-in/out)
;;
;; Any Emacs version:
;;
;; (global-set-key (if (boundp 'mouse-wheel-down-event) ; Emacs 22+
;; (vector (list 'control
;; mouse-wheel-down-event))
;; [C-mouse-wheel]) ; Emacs 20, 21
;; 'zoom-in)
;; (when (boundp 'mouse-wheel-up-event) ; Emacs 22+
;; (global-set-key (vector (list 'control mouse-wheel-up-event))
;; 'zoom-out))
;;
;; (global-set-key [S-mouse-1] 'zoom-in)
;; (global-set-key [C-S-mouse-1] 'zoom-out)
;; ;; Get rid of `mouse-set-font' or `mouse-appearance-menu':
;; (global-set-key [S-down-mouse-1] nil)
;;
;; The first two of the mouse bindings mean that in Emacs 22 or later
;; you can hold the Control key and rotate the mouse wheel to zoom in
;; and out, just as you might do in a Web browser.
;;
;; (In Emacs 20 and 21, Control plus mouse wheeling zooms in, but to
;; zoom out you need to use `C--' before wheeling with Control. This
;; is because Emacs 20 and 21 do not have separate events for the
;; mouse wheel directions, and it is the prefix arg, not the wheel
;; direction, that determines the effect.)
;;
;;
;; See also these files for other frame commands:
;;
;; `autofit-frame.el' - Automatically fit each frame to its
;; selected window. Uses `fit-frame.el'.
;;
;; `fit-frame.el' - 1) Fit a frame to its selected window.
;; 2) Incrementally resize a frame.
;;
;; `doremi-frm.el' - Incrementally adjust frame properties
;; using arrow keys and/or mouse wheel.
;;
;; `frame-cmds.el' - Miscellaneous frame and window commands.
;;
;; `thumb-frm.el' - Shrink frames to a thumbnail size and
;; restore them again.

"Zoom current frame or buffer in or out.
A prefix arg determines the behavior, as follows:
none : Use 1 as the zoom amount.
plain `C-u': Toggle between zooming frame and zooming buffer.
0 : Unzoom: reset size to the default.
other : Use the numeric value as the zoom amount.
Similar to the behavior of command `text-scale-adjust', you can
continue to use any of the keys `+', `-', `0', and `C-u' repeatedly.
The zoom amount from the initial key sequence is used each time.
Example: `C-3 C-x C-- C-- C-- C--' zooms out 4 times with a zoom
amount of 3 each time.
The zoom amount for frame zooming is a point-size increment/decrement.
The zoom amount for buffer zooming is a number of text-scaling steps.
Frame zooming uses command `zoom-frm-in'.
Buffer zooming uses command `text-scale-increase'.
User option `zoom-frame/buffer' determines the default zoom type:
frame or buffer. If the option value is `buffer' and you never use
plain `C-u' with this command then it acts like `text-scale-adjust'."
