[MPlayer-users] Missing mystery parameter

[Graham Lawrence]

I have added the following to ~/.mplayer/config

CTRL+RIGHT change_rectangle 0 16    # move right line right
CTRL+LEFT change_rectangle 0 -16    # move right line left
CTRL+DOWN change_rectangle 1 16   # move bottom line down
CTRL+UP change_rectangle 1 -16    # move bottom line up
CTRL+SHIFT+LEFT change_rectangle 2 -2   # move whole rectangle left
CTRL+SHIFT+RIGHT change_rectangle 2 2   # move whole rectangle right
CTRL+SHIFT+UP change_rectangle 3 -2   # move whole rectangle up
CTRL+SHIFT+DOWN change_rectangle 3 2    # move whole rectangle down

But trying to use them produces this result

mplayer VTS_01_1.VOB -vf rectangle=640:480
Option CTRL+RIGHT needs a parameter at line 163
Option CTRL+LEFT needs a parameter at line 164
Option CTRL+DOWN needs a parameter at line 165
Option CTRL+UP needs a parameter at line 166
Option CTRL+SHIFT+LEFT needs a parameter at line 167
Option CTRL+SHIFT+RIGHT needs a parameter at line 168
Option CTRL+SHIFT+UP needs a parameter at line 169
Option CTRL+SHIFT+DOWN needs a parameter at line 170

Which parameter am I missing?  All the examples of this process I've
found have the same structure that I've used here.
