IIRC there's some key combination to activate the mouse outside the Clipboard but I can't remember it. Ctrl + H maybe???
Seems like there was a command in the past, like you, I have forgotten what it was or is, if it is still available...
Looking through the AH website Help/all sub categories, I was unable to find it....
I have not checked the New Trainers website or AHWiki yet though...
