I have been using Screen4 and the one Klaus built. I have built a screen by mostly copying & pasting from other screens. I added 7 new buttons and assigned them to Alt-Q,W,E,R,A,S, and D keys. All work except for Alt-A. I tried to see if Alt-A was already mapped, but could not find any existing assignments. Can anyone shed some light on my delima? Thanks in advance.
