Slide in Menu

Hey i was wondering if there was any way i could create a menu that slid onto the page when you went close to the side of the swf. The basic idea would be that the menu would be hidden off the left hand side of the screen and when you moved your mouse a set distance towards the left hand side the menu would slide in and when you moved it away it would slide back again.

If anyone can help me please do… thanks

James
