# KEYBINDINGS
# ==============================================================
# The "bind" command assign keys to (internal) commands
# SCREEN checks all the keys you type; you type the key
# which is known as the "command character" then SCREEN
# eats this key, too, and checks whether this key is
# "bound" to a command.  If so then SCREEN will execute it.
#
# The command "bind" allows you to chose which keys
# will be assigned to the commands.
#
# Some commands are bound to several keys -
# usually to both some letter and its corresponding
# control key combination, eg the command
# "(create) screen" is bound to both 'c' and '^C'.
#
# The following list shows the default bindings:
#
# break       ^B b
# clear       C
# colon       :
# copy        ^[ [
# detach      ^D d
# digraph     ^V
# displays    *
# dumptermcap .
# fit         F
# flow        ^F f
# focus       ^I

# bind D pow_detach
# bind F fit
# bind H log
# bind I login on
# bind K kill
# bind L login
# bind M monitor
# bind N number
# bind O login off
# bind Q only
# bind S split
# bind W width
# bind X remove
# bind Z reset

# Let's remove some dangerous key bindings ...

# Current ssh-agent + screen fix:
#
# I have this in my .zshrc file:
# alias attach='$HOME/sh/grabssh.sh; screen -x'
# if [ "$WINDOW" != '' ]; then
#     alias ssh=". $HOME/sh/fixssh; ssh"
# fi
#
# The above is used as such:
#
# 1) instead of using 'screen -x', you will use 'attach' to connect to a
#    screen session
# 2) the if statement does a dirty hack to check if you are inside screen
#    - if you are, it will alias ssh to run fixssh first, which will
#      fix your environment so that ssh will work properly
#    - if you are not, it won't alias ssh, preventing any breakage from 
#      being on a host and not inside screen
#
# This is the contents of grabssh:
# ---------
# #!/bin/sh
