Question

Say I have I split-window with C-x 2 or C-x 3 and then I want to widen the active panel with C-x }. I either have to type this command many times over, or I need to know the exact number of columns I want to widen this panel by and do M-<N> C-x }.

But instead what I want is to keep a key pressed down and have the panel expand until I let go. Is this possible?

C-x z works to repeat or you can directly make C-x } repeatable with repeat-macro-def.el.

(require 'repeat-macro-def)
(defun-repeatable enlarge-window)
(defun-repeatable enlarge-window-horizontally)
(global-set-key [remap enlarge-window] 'enlarge-window-repeatable)
(global-set-key [remap enlarge-window-horizontally] 'enlarge-window-horizontally-repeatable)
