-    \brief The ModeManager class implements a mode manager.
+    \brief The ModeManager class manages the activation of modes and the
+    actions in the mode selector's tool bar.
+
+    Modes are implemented with the IMode class. Use the ModeManager to
+    force activation of a mode, or to be notified when the active mode changed.
+
+    The ModeManager also manages the actions that are visible in the mode
+    selector's toolbar. Adding actions to the tool bar should be done very
+    sparingly.
