JavaScript Change Cursor Icon

Question

I already have the conditions and everything worked out, only thing I need is the syntax in JavaScript to change the cursor to the hand, like the user has moused-over a link, and then I need the syntax to change the cursor to the arrow, like they moused-out of the link. Not much to it, just need the JavaScript syntax for changing cursors.

Only thing is this needs to work in IE, FF, Chrome, Safari, and preferably Opera.

Thanks in advance!
