# Instructions
# ------------
#
# 1. Install this script and give it execute permission somewhere in your PATH.
#    For example:
#
#    $ mkdir -p ~/bin
#    $ wget https://raw.github.com/jipumarino/tmux-zoom/master/tmux-zoom.sh -O ~/bin/tmux-zoom.sh
#    $ chmod +x ~/bin/tmux-zoom.sh
# 
# 2. Add a shortcut in your ~/.tmux.conf file:
#
#    bind C-k run "tmux-zoom.sh"
#
# 3. When using this shortcut, the current tmux pane will open in a new window by itself.
#    Running it again in the zoomed window will return it to its original pane. You can have
#    as many zoomed windows as you want.

current=$(tmux display-message -p '#W-#I-#P')
list=$(tmux list-window)
