[MPlayer-users] mirror using key binding

[Zhang Weiwu]

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.
