Multiple tmux prefix key combos?

Question

I've got tmux setup just the way I like it, and my chosen key of prefix is `, because it's so quick and easy to use.

Everything was gravy until I tried using tmux from my phone, which doesn't have a ` key. Is there anyway to additionally bind ^a to the prefix, so I can use BOTH combos at the same time?

Starting with tmux 1.6, you can use the session option prefix2 to specify a second prefix key (e.g. in ~/.tmux.conf):

set-option -g prefix `
set-option -g prefix2 C-a

Note: If you have any bindings or script that use the send-prefix, you can use its -2 option to send the key assigned to prefix2: send-prefix -2.

Prior to tmux 1.6, the prefix option accepted a comma-separated list of keys:

set-option -g prefix `,C-a
