"P" key does not pan.
I tried to investigate to see if Brian had changed this to another key function, so I first tried Ctrl-P. That didn't work so tried Alt-P and the pan icon appeared.
I thought that was it so I de-selected and tried again.
If you just select Alt-P it doesn't work. You have to do Ctrl-P, then Alt-P. !!
I am afraid I got this wrong.
If you press Ctrl-P it does switch you into pan mode. But the pan icon did not appear until I moved the mouse.
Maybe I too should be drinking while I'm writing mine.
