I think the text in User Guide and Options Help now degraded dramatically:
try reading lynx 2.6 users guide - it was written for users, not a very
technical people nor hackers.
Also I hate you <br> tags for every line, it was discussed before a lot.

IMHO the present Options Help is enough:

                                  Show Images

   Text-based browser cannot show images directly, so we have a choice:
   ignore all images without ALT= text string (this is also switched by
   '[' key), show labels (see also "verbose images" for choice between
   [IMAGE] and filename), use links for every image to make it possible
   to download them (also switched by '*' key). Changing these settings
   will not be saved but could be made permanent by changing the
   respective settings in lynx.cfg.
   ^^^^^^^^^^
Perhaps this word may be replaced with actual options name,
though we have not do this before:

say, [-key and *-key help doesn't say what lynx.cfg option is responsible for
its default! We have 100+ lynx.cfg options and Users Guide will be completely
unreadable if we include all the references there. Instead, lynx.cfg comments
should be corrected if necessary to be as clear as possible.
