When configuring and customizing the hotkeys I often would like to check if the proposed hotkey isn’t used for something I would like to keep, or maybe first want to re-assign to something else before i add my hotkey to a different action.
Proposed solution
This idea is founded from InteliJ PHPStorm where you can search a hotkey by name and the actual keystroke. It actually filters the commands used. and is very handy.
