 The widgets will be rendered with time aligned to the left with the keyboard rendered
 below as specified by the direction = "column".
 
+The keyboard widget also specifies two other Lua functions in on_click and on_wheel. Those are invoked
+when user mouse clicks or wheels on widget. The render function specifies a tag, if the user clicks in
+that part of the widget, the tag will be the first argument to the event handler.
