A key press for the E6B would be very nice. It's a tad annoying trying to check it the hard way. (ESC, "click", check, "close", ESC) Just "key press", check, "key press". The end.

However, you will probably see people tell you something along the lines of, "If you fly a certain plane long enough, you'll figure out when you should head back...". Which is true if you stick to a specific plane but not everyone does that.
