hi. i have been using -vf mirror for a dancing tutorial for some time. i am troubled by having to restart the player without the filter when the tutorial goes to sideview. thus i want to have a key binding for the switching. however a quick checking of -input cmdlist did not reveal anything alike. is such key binding possible in mplayer? thanks. p. s. i have to mention "shortcut key" here for googlers who are used to windows terms.
