I'm using OSX 10.8.1 in combination with iTerm2, zsh and tmux via Homebrew.
The beginning of my ~/.tmux.conf file looks like this:
set -g prefix C-a unbind C-b bind-key a send-prefix set -sg escape-time 1
When I start tmux and press C-a c, nothing happens. When I spam C-a c fast enough then some new tabs open up, but not the equivalent count of my command spaming. When I press C-a first followed by c, nothing happens again. Is there a delay issue or what's up with my tmux installation/configuration?
