Here's the official documentation on configuring kitty's modal mappings.

I made this to explore its uses but also because sometimes my fingers trigger the wrong reflex macro and I accidentally change my layout or alter the window size. This guards against that by literally guarding that behavior behind a key combo that puts me into the express context for altering my window/tab layout and arrangement.

To not clutter up your main config, I recommend saving this to its own file and using the include directive to bring it in.

EDIT: learned that you can map the combo that enters the mode to get out of the mode

kitty-mode-window-tab-arrangement (WTA):
