Apple - Move windows around a desktop -- and to different desktops -- using only the keyboard?

Moving windows to another space:

  • SizeUp (still works for me in 10.8)
  • Spacey (stopped working in 10.7)

Moving windows to another display:

  • BetterSnapTool
  • BetterTouchTool
  • Flexiglass
  • Moom
  • Optimal Layout
  • SizeUp
  • Spectacle
  • Window Mover

There are many, many different sharewares out there that let you move windows around using shortcuts. Just look for window manager in the Mac App Store. I would recommend BetterTouchTool. It's a freeware that let's you customize just about anything. For example here is the shortcuts I have created for myself :
