[wmii] I wrote a jump-or-exec

Maybe someone like it.

#----------------------------------------
#
fn jump-or-exec {
     switch(`{read_tags | grep $1}) {
     case $1
     wmiir xwrite /ctl view $1
     case *
     if (test -n $2) {
     run_command $2 &
     }; if not {
     run_command $* &
     }
     }
}

You can call it like is

fn Key-$MODKEY-w { jump-or-exec web iceweasel }
