Switching Instruments With Midi

hey
searched the forum, but didn’t get information.
the usual shortcut for switching to the next or previous instrument is + or - on the numpad. my question: is it possible to link this to buttons on my midikeyboard? that would be more comfortable for live playing.

Cool! Thanks

Is there a way to make it “jump” to another instrument slot instead of crawling there step by step? (other than clicking it with the mouse)
