Mouseless workflow on the Mac

There's a lot of different window managing tools on OS X. I personally use Optimal Layout, but there's a number of open source ones as well, such as Slate [1] (which unfortunately hasn't been updated in a while), Mjolnir (nee Hydra) [2], and Spectacle [3]. Both of the last two were updated a few months ago.

Spectacle is a bit easier to use than Mjolnir, but it looks like Mjolnir is more flexible. In comparing Mjolnir to things like Divvy, the Readme states:

"Mjolnir is intended for programmers who want to write programs that customize their environment. It's not intended to be a drag-n-drop solution; it's meant to allow you to write your own personalized productivity enhancement suite to keep and to use long-term."
