What about moving to the beginning of a line?

I did the same thing but I also mapped Ctrl-\ to send the "prefix" (helpful for neated tmux sessions), so I just hit Ctrl-\ for beginning of line.

(Although this seems to have broken in recent tmux releases on Debian (3.x?) and I haven't looked into yet.)

Ctrl-a + Ctrl-a, works like a charm :)
