By the way I am inclined not to use the word "pass" anywhere in Mojo. I think it's a bad metaphor for how multiboxing programs work,.
Ok, i'll bite. I don't see "action" or "trigger" representing the fuctionality either though. Getting rid of "pass" makes sense - but we should replace it with a proper term that defines the function.

"send" ? (because you're sending keystrokes to one or more targets?)
"broadcast" - obvious to us, but what about non techy geeks?
"inject" - meh - sounds too much like botting
???
