I tried binding a key to this:

$ cat ~/.mplayer/input.conf
\ af_clr

As far as I can tell, mplayer now recognizes \ as a bound key (since it
doesn't give an error about not having a binding), and recognizes af_clr
as a valid command (since it doesn't give an error about the command),
but nonetheless hitting \ does not seem to turn off scaletempo.

On the other hand, the following works:

$ cat ~/.mplayer/input.conf
\ af_del scaletempo

Also, now that I can bind a key to this, I find myself wishing for an
af_toggle.

Handy; now I don't need to edit the config file every time.
