Back button ID

What is an ID of “back” button? I don’t have “back” button on my remote, so I can’t get its ID.

KeyUp = 2
KeyDown = 3
KeyLeft = 4
KeyRight = 5
KeyOk = 6
KeyInfo = 10
KeyRev = 8
KeyFwd = 9
KeyPP = 13 ’ play/pause
KeyBack = ???

I believe it’s 0 (instant replay is 7), but it’s only available via events on the roImageCanvas. All other screens close with the Back button, so the only event is isScreenClosed.

Thank you TheEndless! I’m developing gui in roImageCanvas…
