For example, for all Search Match commands you can do the following:
All start with
CtrlMThen each command starts with
CtrlMCtrlCCtrlMCtrlWCtrlMCtrlPOr maybe if you use it very frequently you can use a more eronomic prefix
CtrlSSo this is very similar to what you can already do with the Menu via Alt+S, C, but the benefit of custom shortcuts is you don't need to see the menu flash if you remember the keybinding. Also it's more flexible as you're not tied to Alt, so you can have more ergonomic keybinds
