     """ Represents a State of Getan
 
     A State can be used to handle user input. The user input handling is done
-    in three phases. First it is possible to filter keys that shouldn't be
-    passed to a widget in input_filter. Afterwards it is possible to redirect
-    a key to a specific widget in keypress. In the third phase it is possible
+    in two phases.
+    First it is possible to redirect a key to a specific widget in keypress.
+    In the second phase it is possible
     to act on user input which isn't handled by a widget yet. The corresponing
     method is handle_input.
