I've recently bought an used Triton Classic, with a brief guide that's useless.
I'm in a hurry, and I need to make some things with combis... but don't know how to

Is it possible to change the parameters of a combi without touching the screen? i.e.: I have a combi for a song, with 6 layered programs, but in some measures I need to make audible only some of those programs (maybe one as solo, maybe only 2 or three layered), and I prefer not to touch the screen, cause it's difficult to focus the target right.
Can I use the SW 1 and 2? Or knobs? or any other way?
And most important: How?
Thanks in advance (sorry for my english)
ps: I forgot to question about the RPPR, but I have time for it. Same problem: no idea about how to make it work, and my manual is... crap
I just want to create a combi with drums, as the factory ones my Triton has. But no way, men
