I've been using tmux for years now, but I keep forgetting the shortcuts for resizing panes.
So, in all it's glory, the shortcut for resizing a pane in tmux is:
(CTRL-B) + ALT/⌥ + (ARROW IN SOME DIRECTION)
I have my tmux prefix set to a
like this:
set -g prefix C-a
unbind C-b
So the actual shortcut I use is:
(CTRL-A) + ALT/⌥ + ↑
