@christoomey, one more question about this episode:
I’ve noticed that when using vim outside of tmux, my timeout settings work such that when I press escape, vim immediately leaves insert mode. However, when I am in tmux, there’s a delay that seems to last about a full second. I assume this is tmux checking for an escape sequence or something similar, but is this a problem you’ve seen, and is there a good solution for it? I looked at your dotfiles and didn’t see anything that stuck out as a way to address this issue.
In case it’s useful, I’m using iTerm2 with the keys set for xterm, but I see the same issue in Terminal.app.
