1. use select button for contextmenu

Sorry, but I might be stupid. But can't figure it out. 
I need context menu for youtube, because I need that option to play all songs from playlist.

If I set in iBusCommunicator addon that Nav button hold is context menu, then I can access it. But then I don't have back button.
If I set that Nav button to be back, I don't know how to get context menu with that select you mentioned. It always just starts playing video.
