I just spent a few minutes trying to figure out how to easily use the keyboard to split the screen between two windows (turns out I needed the Compiz Grid plugin from compiz-fusion-plugins-extra). I also solved a couple of little related issues, like how to properly maximize a window, which the Grid plugin didn't do.
This is good information that I'd love to contribute, and should be out there, but I can't really just make a question and answer it myself, can I? I don't get the impression sockpuppeting is really kosher on stack sites.
Is there any good way of handling this kind of situation?
