I often wish to be able to open the window selector applet with a keyboard
shortcut.  I wish the Keyboard Preferences capplet would allow me to specify
one, next to the shortcuts for the application menu and the run dialog.

The window selector is very convenient when you want to find a particular window
on a different workspace, and you don't remember exactly on which workspace you
left it.  Having to use the mouse is not always convenient, especially when you
use a dual-head setup and can no longer just throw the mouse pointer to the
corner of the screen.  With a keyboard it would just be Alt-Fwhatever, Down,
Down, Down, Enter.
