I use spaces for having multiple desktops, but often need to move a program from one space to another.

I am aware of the various ways to do that with a mouse:

• Click window drag to edge
• F8 to show all spaces and drag to desired location
• Click window and use ctrl-# or ctrl-Arrow

But have not been able to find a keyboard-only method. I use Linux for one of my primary workstations which has this ability and I would LOVE to use it with OSX as well.
