Moving a window that's off screen or otherwise hidden.

When using Windows, you may run into the problem of trying to access a window that is not visible because it is far off the screen or hidden under something. This is not a bad trick to remember, from Raymond Chen:

The basic idea is select the window in the taskbar, then hit Alt-Space, M, hit an arrow key, and then move the mouse.

Unfortunately, it doesn't seem to work in the case where the window is hidden under a VMWare Player window, which occasionally commandeers my entire secondary monitor.
