Suggest appendix in User Guide for key shortcuts

[William_Ince]

This would make a nice sticky (hint).

From my cheat sheet:

Installation Guide REV AA

Button 1: Hold to shut down or hold to turn on Skyview - page 3-7
Buttons 1,2,5: Press all together to reboot Skyview - page 3-8
Buttons 2,7: Press together for Screenshot - page 21-2
Buttons 7,8: Hold to enter setup menu. - page 3-9

Would rather see this in User Guide . . . for all us users.
There are probably a few more key combinations that would also be very helpful.
