I'm using tmux as a replacement for GNU screen, and I'm using set-option -g prefix C-a to use C-a as my default. This naturally conflicts with C-a as the emacs-style move to beginning of line shortcut.

In screen, C-a a sends a C-a event to the shell, but I can't figure out how to duplicate this functionality in tmux.

For your .tmux.conf:
