Using the pad numbers from a midi keyboard as well as the play and pause buttons in musescore.

I have a Roland juno-ds and i feel i must be a way to asign the numbers to select the diferent measures (as you do with the computer keyboard). Also in other programs you can use the play and pause buttons from the midi keyboard to play and pause in the program. I feel it must be possible with musescore but i can't find how. It whould make writing so much comfortable because now i have to jump up and down betwen the computer and the music keyboard.
