Time to Move The Rectangle

Hello All,

I have a simple issue, which is driving me nuts!  I have a sketched rectangle on the front plane (solid).  All I need to do, is move the rectangle horizontally so the middle of the rectangle is in the middle of the extruded solid; I know this should be very easy, but I'm not having any luck.  I tried quick snap, midpoints but that didn't work. I do remember I once did this by manually moving a sketch over by using the arrows, I think. But I cant remember how to do that...

Thanks for the help

Charles
