Short Cut For Tones

Hello I would like to know it there is a short cut for the note of samples like f12 in fast tracker… did you remember?
I don’t like change my note in instrument - split halftone…
Maybe it’s better with a midikeyboard?

I never really used Fast Tracker, so I don’t remember what F12 did. Can you please explain in a bit more detail what functionality you’re after?
