Search bar in cheatsheet

[noclone]

Is your feature request related to a problem? Please describe. There are a lot of bindings displayed in the cheatsheet, it can be hard to find a specific option or bind.

Describe the solution you'd like A search bar at the top of the cheatsheet to filter the rows would be great, with an option to filter by keybind instead of word. This would allow to quickly find the option you are looking for, or to check if it exists. The "filter by keybind" option would allow to quickly check if a key is already taken or if it is available to bind to a new option.
