Reverse keystroke lookup

I think it would be great to be able to reverse lookup key commands. For instance in the search section if I pressed backspace then all the commands that I have with backspace assigned would appear. This would make it a bit easier for custom key commands. For example I like to use backspace to return to start. And to easily find that command I would search “backspace” in order to assign it to a new key command. Such as “shift+1” for example.

Possibly this is available? Anyone know of a way?

Start by having a closer look a the key commands window.
