Is there way to force what is within onmouseover?

[rughar]

Hello.

I wonder if I can have a function which set some unit (eg. raid1) or UnitGUID as my mouseover unit without actually move my mouse over the unit. I would like to put this function into "OnEnter" script for some frame and drop the mousever at "OnLeave".

I believe that pretty much same thing is achieved by addons like Grid. When you move your mouse over a frame, it acts like you actually move your mouse over that unit. I tried to dig this functionality from the Grid2 code without success. Can anyone help me with this please?
