This library defines a global minor mode called wn-mode that adds keyboard shortcuts to quickly switch between visible windows within the current Emacs frame.
Install it via MELPA with:
M-x package-install RET wn-mode RET
To activate, simply add
(wn-mode)
to your ~/.emacs.
By default, the shortcuts are M-1, ..., M-9 for selecting windows #1 through #9. M-0 selects the minibuffer, if active. M-# interactively asks which window to select.
With a prefix argument, swaps the buffers between the current and target windows.
Customize wn-keybinding-format if you wish to use different key
bindings, e.g.:
(setq wn-keybinding-format "C-c %s")
Re-enable wn-mode and the new keybindings will take effect.
