I assume you mean to use the arrow keys in the menu to move, and you don't want the walk gani to commence, am I correct?
If that is the case, you should look into the commands disabledefmovement & enabledefmovement, or so.
These commands will disable movement and enable it, respectively.
It would be useful if you wanted to be able to use the arrow keys in the menu to select things, yet the player would not move and the gani would not play, and thus no walking sound.
