A mouseless tale: trying for a keyboard-driven desktop

The computer mouse is a wonderful invention, but for the past few
months I've been working to use mine as little as possible for
productivity and ergonomic reasons. It should not be surprising that
there are quite a few open-source applications, utilities, and
configuration options that are either designed to or incidentally
assist in creating a keyboard-driven desktop. This includes tiling window
management with PaperWM, the Vimium browser extension, Input Remapper, and more.
