[mostlysimilar]

iTerm split panes use such intuitive keybinds I find myself changing other software with similar functionality to match, e.g.

split pane vertical: cmd + D

split pane horizontal: cmd + shift + D

focus pane left: cmd + [

focus pane right: cmd + ]

Just gold standard imo. tmux is great software and very useful on remote machines but its keybinds don't come close.
