* How to use
|

- =select-window-[0..9]=
|
||||
|
||||
Use ~M-1~ to ~M-9~ to navigate windows numbered 1 to 9.
|
||||
| Key binding | Description |
|
||||
|-------------+---------------------------------------------------------------------------------------------|
|
||||
| ~C-x w <n>~ | select window <n>, where <n> ranges from 0 to 9. A negative argument deletes the window. |
|
||||
| ~C-x w `~ | select window by number. Number can be given as prefix arg or will be read from minibuffer. |
|
||||
|
||||
By default, ~M-0~ is bound to =select-window-0-or-10=, which behaves like
|
||||
the other ones except that if 0 is not assigned it will act on the window 10
|
||||
instead.
|
||||
- =select-window-0-or-10=
|
||||
|
||||
By default, ~C-x w 0~ is bound to =select-window-0-or-10=c. If window 0 is not
|
||||
assigned, it will act on the window 10 instead.
|
||||
|
||||
You can rebind this to the more straightforward =select-window-0= if you
|
||||
prefer.

- =select-window-by-number=
|
||||
|
||||
If you happen to have more than 10 windows, you can use the
|
||||
=select-window-by-number= function, bound by default to ~C-`~.
|
||||
=select-window-by-number= function, bound by default to ~C-x w `~.
|
||||
|
||||
This function allows several ways to input the window number:
|
||||
|
||||
- Use a numbered prefix argument.\\
|
||||
*Ex:* ~C-1 C-2 C`~ to select window 12.
|
||||
*Ex:* ~C-1 C-2 C-x w `~ to select window 12.
|
||||
- Use a negative prefix argument to delete the window.\\
|
||||
*Ex:* ~C-- C-1 C-2 C`~ to delete window 12.
|
||||
*Ex:* ~C-- C-1 C-2 C-x w `~ to delete window 12.
|
||||
- Use the negative prefix argument to delete window 0.\\
|
||||
*Ex:* ~C-- C-`~ to delete window 0.
|
||||
*Ex:* ~C-- C-x w `~ to delete window 0.
|
||||
- Use the default prefix argument to delete current window.\\
|
||||
*Ex:* ~C-u C-`~ to delete current window.
|
||||
*Ex:* ~C-u C-x w `~ to delete current window.
|
||||
- If no prefix argument ig given, a number is read from minibuffer. A negative
|
||||
input will delete the window instead of selecting it.
|
||||
|
||||
*NB:* On Spacemacs you can specify the prefix argument using ~SPC u~.
|
||||
*Ex:* ~SPC u - 1 2 C-`~ to delete window 12.

* Configuration
|
||||
|
||||
** Keybindings
|
||||
To define your own bindings and override the default ones, override
|
||||
=winum-keymap= before activating the mode:
|
||||
|
||||
By default, all key bindings are prefixed with a value stored in
|
||||
=winum-keymap-prefix=, by default ~C-x w~. See [[Customize options][Customize options]].
|
||||
|
||||
The default prefix is ~C-x w~ for compatibility with common Emacs bindings. If
|
||||
you prefer no to use a prefix and have shorter key bindings, you can also
|
||||
override =winum-keymap= before activating =winum-mode=:
|
||||
|
||||
#+BEGIN_SRC emacs-lisp
|
||||
(require 'winum)
|
||||
|
||||
(setq winum-keymap (let ((map (make-sparse-keymap)))
|
||||
(define-key map "\M-m 0" 'select-window-0)
|
||||
; ...
|
||||
(define-key map "\M-m 9" 'select-window-9)
|
||||

||||

|
||||

||||
