Havoc Pennington eb647577c3 don't start the cycle process if the binding for switching windows has no
2002-10-18  Havoc Pennington  <hp@redhat.com>

	* src/keybindings.c (do_choose_window): don't start the cycle
	process if the binding for switching windows has no modifier bits,
	just focus the window immediately.

	* src/prefs.c, src/keybindings.c: add a keybinding to move between
	windows that goes in the opposite direction.  This is mostly
	useful if you want to bind unmodified keys to the switch windows
	functions, e.g. if you have "Forward" and "Back" keys on your
	keyboard. Patch from Shilad Sen <shilad sourcelight com>
