 <para>The Task Switcher is often invoked using the key combination <keycombo>&Alt;&Tab;</keycombo>, but this can be changed. When invoked, it shows a list of all the currently open windows, optionally filtered and augmented according to the configuration settings. For example, the list may be filtered to show only windows that meet certain criteria, such as windows that are currently visible.  Once the window list is shown, the user can cycle forward and backward through all the listed windows by repeatedly hitting the Task Switcher key combination.  Releasing the Task Switcher key combination will activate the window that was selected in the list.</para>
 
 <para>Because the Task Switcher offers so many configuration options, two distinct collections of configuration settings can be defined. These collections are called <guilabel>Main</guilabel> and <guilabel>Alternative</guilabel>, and each can have a unique set of key combinations assigned to them.</para>
