+{\bf NB: } Note the difference between methods like 
+\helpref{LeftDown}{wxmouseeventleftdown} and 
+\helpref{LeftIsDown}{wxmouseeventleftisdown}: the formet returns {\tt TRUE}
+when the event corresponds to the left mouse button click while the latter
+returns {\tt TRUE} if the left mouse button is currently being pressed. For
+example, when the user is dragging the mouse you can use 
+\helpref{LeftIsDown}{wxmouseeventleftisdown} to test
+whether the left mouse button is (still) depressed. Also, by convention, if
+\helpref{LeftDown}{wxmouseeventleftdown} returns {\tt TRUE}, 
+\helpref{LeftIsDown}{wxmouseeventleftisdown} will also return {\tt TRUE} in
+wxWindows whatever the underlying GUI behaviour is (which is
+platform-dependent). The same applies, of course, to other mouse buttons as
+well.
