+  By default, Emacs supports all the normal mouse actions like setting
+the cursor by clicking on the left mouse button, and selecting an area
+by dragging the mouse cursor.  All mouse actions can be bound to
+commands in the same way you bind keyboard events (@pxref{Keys}).

+@cindex mouse-1
+  When you click the left mouse button, Emacs receives a @code{mouse-1}
+event.  To see what command that event is bound to, you can say
+@kbd{C-h c} and then use the left mouse button.  Similarly, the middle
+mouse button is @code{mouse-2} and the left mouse button is
+@code{mouse-3}.  If you have a mouse with a wheel, the wheel events
+are commonly bound to @code{mouse-4} and @code{mouse-5}, but that
+depends on the device.
+
+  For mouse-wheel events can also be @code{wheel-up} or
+@code{wheel-down}, and the easiest way to tell is to just use @kbd{C-h
+c} and then use the mouse.
+
+  You can also combine keyboard modifiers with mouse events, so you
+can bind a special command that triggers when you, for instance, holds
+down the Meta key and then uses the middle mouse button.  In that
+case, the event name will be @code{M-mouse-2}.
+
+  On some systems, you can also bind commands for handling touch
+screen events.  In that case, the events are called
+@code{touchscreen-update} and @code{touchscreen-end}.
