standard r/o keybindings

standard r/o keybindings

[Sam Steingold]

M-x rgrep quit-window RET *.el RET emacs/lisp RET
will show ~60 places were quit-window is bound to "q".

Proposal:

add

(defvar read-only-buffer-mode-map
  (let ((map (make-sparse-keymap)))
    (define-key map "g" 'revert-buffer)
    (define-key map "q" 'quit-window)
    (define-key map "z" 'kill-this-buffer)
    (define-key map " " 'scroll-down)
    (define-key map "DEL" 'scroll-up)
    .......
    map))

to, say, simple.el
and (set-keymap-parent ... read-only-buffer-mode-map)
to all the r/o mode map definitions.

pro:
- uniform user experience in all r/o buffers
- ease of development (less code to write)

contra:
- some modes _might_ have to modify their own bindings
  (very few and they can override the standard binding anyway)

note that we already have a good candidate for
read-only-buffer-mode-map: view-mode-map.

XML is like violence. If it doesn't solve the problem, use more.

Such modes should probably inherit from special-mode.  Maybe some do,
and their keymaps have not been revised.  Cleanups welcome.
