They don't really work that way. You can check for an offset of the 
button contents and set the label accordingly. Or you can change the 
menuhistory to automatically insert the desired line, but the menu won't 
pop up like you want it to. The menu portion is pretty much a 
manual-only control, just as you can't pop down a system menu via script 
either.
