# for some reason this is wrapping at 80 cols, using save- instead of show- helps
# -b for background is needed because xclip continues to run to service the clipboard paste reqeusts until the 
# clipboard buffer is replaced with some new contents
#bind C-y run-shell -b "tmux save-buffer - | DISPLAY=$(<~/.xdisplay) xclip -selection clipboard -in && tmux display-message 'xclipped successfully'"

# this was just for testing, but interestingly for some reason tmux-show-buffer >/tmp/t never terminates, writing to a pipe works fine??
