Question

Is there anyway to clear everything off the screen so you can take a clear screenshot like in WoW where you hit ctrl z or whatever it is?

ctrl+shift+h was what mine was...

ctrl-shift-PrintScreen

ctrl-shift-h turns off the interface until you repeat those steps turn it back on. (You hold down the ctrl and shift as you type h.)

Ctrl-Shift-print screen turns it off for the duration of taking the shot.

actually shift + printscreen will give you a clean shot no ctrl needed
