UMG get hud not available


My HUD contains a variable called TIME.
I have a UMG widget on my HUD.

The healthbar works. I can do get player pawn.
But i see its not possible to do a get HUD.

Firstly i would like to understand why its not possible to do a get HUD.
Also i would like to find out how would i then go about getting an interface event coming from the HUD if i cannot cast or get HUD from the UMG Graph editor.

Ok. For some reason on the 4.5 preview, get HUD is now hidden. You have to tick the Context Sensitive box before it is shown.
