Okay, I really hadn't thought much about that, but you guys got my interest up...
If a button has a link to an IR code or macro the the pressed state just kinda blinks on and then off.

If a button has a page jump and you just tap the button the pressed state again blinks on and then off, but if you give the button a very slight hold time with you finger then the pressed state stays on the screen until the jump occurs.
