doKeyDown method

void doKeyDown()

The diagram will call this method upon a key down event. By default this just calls #doCancel if the key is the ESCAPE key. Implementations of this method can look at Diagram#lastInput to get the key.

This method may be overridden. Please read the Introduction page on Extensions for how to override methods and how to call this base method. @expose
