ctrl+b not being recognized

[Osman Pontes]

Hey everyone, I use tmux and it works properly, but when I use tmate it doesn't recognize ctrl+b, which makes my tmate usage incomplete.
Do anyone face the same problem and know what's happening?
I have a .tmate.conf that is a copy of my .tmux.conf.
Thank you in advance!

I needed to add this to my .tmate.conf:

set -g prefix ^b

Also I needed to change this line from:

bind \\ split-window -h -c '#{pane_current_path}'

to

bind \ split-window -h -c '#{pane_current_path}'

It's interesting because the requirement for \\ is for new tmux versions. Is tmate up to date with tmux?
