 usr/share/byobu/keybindings/f-keys.tmux.disable,  
 usr/share/doc/byobu/help.tmux.txt: LP: #817686   - add a couple of
 (tmux-only) modes to byobu-select-profile, which can     automatically change
 the background color of the status bar, based     on the systems hostname, ip
 address, or just at random   - map this to Ctrl-F8
