Think a better way before every keystoke.

###getty

You can access up to 6 consoles by default, with the keystrokes Ctrl-Alt-F1 to Ctrl-Alt-F6.
These are running getty on tty1 to tty6. From within one of these consoles, to change to another one, use either Ctrl-Alt-F/num/ or Alt-F/num/.
X is running on Alt-F7.
