Shortcuts for [kt], [?] and [!]

[Stuurrm]

I personally use all of the notes quite often and it would be nice if a shortcut for them would exist in the same manner as for example [f].
All of the easy right click + something have been taken so I believe there to be 2 sensible options.

1. Make it so you have to press 3 buttons when making them. The third key could easily be "z" as that is close to the left shift etc.
2. Break away from the convention of using right click for notes and start using mouse 3 + shift, ctrl etc.

PS. The notes on the title are the most used ones without shortcuts but there is also the special notes of [x] and [cl] which get used sometimes.

not everyone has mouse 3 right? like you could be on a touchpad.
i dont care too much either way
