Shawk,
Correct me if I'm wrong but you want to be able to open E6B without using the mouse?
It would seem to me that you could accomplish this by opening E6B on climbout and just close/minimize the clipboard so that when your all shot up and dont have a free hand that all you'd need do is open the clipboard and E6B would be displayed.
I have another question if you dont mind,if you dont have a free hand to use the mouse would you have the dot command programed like you have the .ef?
Personally,I like the idea myself but it's sort of redundant as a single keystroke will do this provided you set the clipboard up when you start a new sortie,then again your wish would remove the need to setup the clipboard.
