9wm is an X11 window manager inspired by the Plan 9 window manager 8½. It provides a very simple and clean user interface. It makes heavy use of the mouse, and no use of the keyboard. It is click-to-type. It uses the X11 font system (which, unfortunately, means no Unicode support).
9wm does not provide virtual desktops, customization, key bindings, or compositing. It does not allocate any colors, and only requires Xlib, both of which will be great news if you are in 1993.

The focused window has a black border. Mouse and keyboard events go to this window. Left click a non-focused window (white border) to focus it.
Right-click anywhere other than the focused window, including in any non-focused window, to bring up a menu. All further actions are done with the right mouse button. The menu has options for:
Beneath the first 5 items are a list of all hidden windows.
Middle-click anywhere other than the focused window to run "mm mouse2". It's up to you to write an "mm" program and put it in your path somewhere, if you want to use this for something. I have mine run "google-chrome-stable --show-app-list".
