Add shortcuts for launcher favorites and clipboard history

Is your feature request related to a problem? Please describe.

when I have pins / favorites elements, I can't press cmd + 1, cmd + 2, ... to select them, I have to click on the element to select it.

Describe the solution you'd like

You should add something like I did on Tinycat in PR 340. It's written in swift but you get the idea : it should support multiple keyboard layouts and cross OS (ctrl and cmd).

Describe alternatives you've considered

The mapping uses hardware key codes rather than the character produced by the keyboard layout. This makes the shortcuts work consistently on layouts such as QWERTY and AZERTY.

You can also add a section to remap those shortcuts if you want to better support all keyboard layouts

Additional context

This is what it looks like in Tinycast.

PS: I mentioned the root palette and cipboard history but maybe it could be shared across all the launcher I don't know the other usages
