Subject: vestigial elisp manual descriptions of obsolete variables
 mouse-wheel-up/down-event 
Date: Fri, 7 Mar 2025 08:48:58 -0500

The following paragraph in the elisp manual section "Miscellaneous System Events" describes blinding events based on the now obsolete variables `mouse-wheel-down-event', etc.:

>      The ‘wheel-up’ and ‘wheel-down’ events are generated only on some
>      kinds of systems.  On other systems, other events like ‘mouse-4’
>      and ‘mouse-5’ are used instead.  Portable code should handle both
>      ‘wheel-up’ and ‘wheel-down’ events as well as the events specified
>      in the variables ‘mouse-wheel-up-event’ and
>      ‘mouse-wheel-down-event’, defined in ‘mwheel.el’.  Beware that for
>      historical reasons the ‘mouse-wheel-_up_-event’ is the variable
>      that holds an event that should be handled similarly to
>      ‘wheel-_down_’ and vice versa.
