The mousebutton element identifies the conventional name of a mouse button. Because mouse buttons are not physically labeled, the name is just that, a convention. Adding explicit markup for the naming of mouse buttons allows easier translation from one convention to another and might allow an online system to adapt to right- or lefthanded usage.
