# $1: title (mandatory)
# $2: program to run, no quotes in here! (mandatory)
# $3: explicit arguments to screen, you have to add -t title here yourself! (optional)
# $4: desired number for the new screen (optional)
# $5: screen command (!) to run, if already selected, e.g. eval 'stuff foo' (optional)

# use via e.g.:
# bind m screen screen-select-or-run mutt mutt
# bind m exec screen-select-or-run mutt mutt '-ln -t mutt' 1 q

# the 'screen' variant is faster but will open an intermediate screen
# also *if* the "stuff" actions ever work, I think they might work
# with 'exec' rather than 'screen'
