True, I try !execute [] as a desperate last-resort heuristic for another way to group words when things don't seem to work :D

I think only layercut might do something special; it requires wrapping actions in two !execute []'s in deprecated support of both a left and right -click action for shortcuts.

Some themers wrap all actions in an !execute [] out of habit though, perhaps out of it being more readable, memorable or easily edited to add more actions--all small details.
