This causes a bug when you map this to other commands.
In mac, it’s common to map forward and back to cmd + ] and cmd + [ (See https://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts).
Because I’m used to this, I’ve remapped Navigate Back and Forward to these commands. But, there seems to be a hotkey to indent and unindent already mapped to these hotkeys – this is not listed in the hotkeys list in settings though so the result is that cmd + ] and cmd + [ both navigate forward / back and indent and unindent.
