Hold down the Alt key and press the Tab key repeatedly to walk through the windows on the current desktop (the Alt+Tab combination can be reconfigured). If this checkbox is checked a popup widget is shown, displaying the icons of all windows to walk through and the title of the currently selected one. Otherwise, the focus is passed to a new window each time Tab is pressed, with no popup widget. In addition, the previously activated window will be sent to the back in this mode.
