# GNU screen password bug on my mac. I can either custom code a work-around
# or switch to tmux. Tired of really dirty hacks to make screen do what I want,
# and what other things support as first class citizens.
#
# I'm sorry, screen, it's been really wonderful, but I need to take a
# break.

# I use esc lots for vim. By default, tmux holds on to esc characters
# for 500ms, which is _more_ than enough for me to hit esc three times,
# and then start typing commands a bunch...
#
# Tune this better if you use esc for tmux keymaps, I guess.
