Redefining the Command key
Emacs uses ‘C-a’ for ‘beginning-of-line’. It is also the command key for GNU Screen, which causes a problem of “muscle memory impedance matching.”
Suggestions for Command key Redefinition

# ##Control-^ (usually Control-Shift-6) is traditional and the only key not used by emacs
