...right - the principle of what you wish to achieve is simple. However,
Greenstone doesn't support either at present - I'll explain more about this
in the rest of the message.

...that applies within the document - i.e. to link to the next or previous
section of the same document. It doesn't support moving between documents.
Furthermore, when you ask about moving across documents, it is worthwhile
remembering that an AZList is a permanent list, so the same document always
comes next, unless one has just performed a rebuild of the index. On the
other hand, a search result list is a temporary list, and one would have to,
in effect, rerun the search and find the catalogue number for the next
document. Therefore, providing that "dynamic" facility would require more
effort than providing a movement through a permanent list.

To add the facility you require would require some additional programming of
Greenstone to ensure that the buttons linked to the correct document. This
would probably require the services of an experienced programmer.

I'm sorry not to be of more immediate help, but I trust that the above is of
some assistance...
