Windows 7 has a neat feature where the Windows Key in conjunction with the arrow keys tiles the active window. Windows key + left arrow moves it to the left half, windows key + right arrow moves your window to the right half of your monitor.
Is there an equivalent to this functionality in OS X?
Can anyone suggest some alternative metaphors by which to manage my windows? I find that OSX windows tend to be a bit more scatterbrained than their windows counterparts.
