Some mice on the Windows platform support a mouse wheel which is used
for scrolling documents without using the scrollbars. By rolling the
wheel, the system will generate \fBMouseWheel\fR events that the

+the event is routed to the window under the pointer. When the event
is received you can use the \fB%D\fR substitution to get the
\fIdelta\fR field for the event which is a integer value of motion
that the mouse wheel has moved. The smallest value for which the
system will report is defined by the OS. On Windows 95 & 98 machines
this value is at least 120 before it is reported. However, higher
