Question about glossary terms

[Roger Bell]

I am creating unstructured guides in FrameMaker 7.2. The guides are
primarily for print, but our customers also received PDF copies.
 
There are terms that I need to define, so I have created a glossary. I
want to use a visual indicator, so that anyone using either the print or
the PDF guide would know that a term is defined in the glossary.
 
So far I have been using a graphic question mark icon that I place
directly beside a term. I describe the meaning of the icon in the
typographical conventions section of each guide's introduction.
 
Any thoughts on a better way to indicate glossary entries? I am not
wanting to use a cross-reference or hyperlink in particular, but I'm
willing to consider all suggestions.
