Snapping windows (left and right)

I really like the feature in windows that allows me to quickly move and tap my window left and right and it automatically resizes to 50% of the screen.  If I'm in dual display mode I can use the Windows key + Right and left arrow to accomplish the same.  I can't seem to find away to do this in BackSlash.  Is there a method that I can't find yet?

Thanks,
Randy
