Here's another small script, this one more of an "entertainment" type script.
All it does is rotate the model in the 3D viewport.
To set it up:
copy AutoRotate.js and AutoRotate.htm into the Moi/commands directory.
Then open MoI, go to the Options dialog, Shortcut keys and add entries for:
R AutoRotate
Ctrl+R AutoRotate Right
Alt+R AutoRotate Up
Shift+R AutoRotate Down
The command parameters available are Left,Right,Up,and Down.

The default direction of rotation is left, but can be changed in the
AutoRotate.js file by changing the variable "direction".

The default rotation angle is 0.25, but can be changed by setting
the "rotation_angle" variable.
A smaller angle = slower rotation, larger angle = faster.
