I assigned a button to "mouse pan toggle". Hit that button when clipboard is not up and mouse mimics head movement.
It works the same as F8 command. The second clipboard map comes up, it goes back to normal F1 view mode (no mouse pan).
I got used to using the "mouse pan toggle" button, when we were testing mouse control for aircraft. I recommend to having it set just in case... unless you have TrackIR.
