I greatly appreciate your answer but there is no 'pressed state' for this icon. When I try to look at the properties it says "no properties available."

Perhaps I didn't make my question clear enough... Daniel has a little icon in the top, right corner of his layout. The icon is three curved bars, one slightly larger than the next, that looks like a radio frequency transmission symbol being emitted. When any other icon on the screen is pressed this little transmission icon blinks in a manner that simulates a transmission being sent. I would like to re-create this effect with another graphic.

Anyone...? Beuhler...?
