+    InspectionFrame window where the widget under the mouse cursor
+    will be selected in the tree and loaded into the shell's namespace
+    as 'obj'.  The default key sequence to activate the inspector is
+    Ctrl-Alt-I (or Cmd-Alt-I on Mac) but this can be changed via
+    parameters to the `Init` method, or the application can call
+    `ShowInspectionTool` from other event handlers if desired.
+
+    To use this class simply derive a class from wx.App and
+    InspectionMixin and then call the `Init` method from the app's
+    OnInit.
