Multiple simultaneous actions being executed at the same time are not 
currently supported for good reasons (I explained several times why in 
the forum, but in essence: it will not work when f.ex. you'd be trying 
to cut and paste at the same time, using Apple+C and Apple+V - the 
system would only see Apple + C + V - it gets worse when other 
modifiers come into play - therefore Remote Buddy takes care that such 
combinations can't happen), but that doesn't mean it will never be 
supported - Remote Buddy is under very active development after all ;-)
