Hmm...
Sit, down, stay, wait. Jump, jump long, weave, tunnel, chute, climb, teeter, walk it, table, drop... we use "eeeeasy" too. Touch. Out, around, here... I'm trying to run through a course in my head and think of what we use... "Go" also, and "okay" as a release from the 2o2o... "watch me" isn't a command that's used on course, so to speak, but I think it still counts.
Okay, that's all I can think of right now, LOL. That's 22.
