After conversion, the ROLLUP/ROLLDOWN keywords are represented as a push
buttons on the Web page. These buttons will replace the use of the Page Down/Page
Up keys on the user's keyboard respectively. If ROLLUP or ROLLDOWN is disabled
in the DDS source, no push button will be placed on the converted Web page
for the disabled keyword. The optional text is ignored by conversion,
however, it is still included on the list created at program compilation time
to explain the intended use of the indicator. This text has no function in
the file or the program other than as a comment.
