Glossary with entries without reference

Question

Is there a command so that the glossary will also display elements without links (an equivalent of \nocite in BibTeX)?

Answer 1

Quoting p. 47 of the glossaries documentation:

It is possible to add a line in the glossary file without generating any text at that point in the document using:

\glsadd[<options>]{<label>}

[...]

To add all entries that have been defined, use:

\glsaddall[<options>]
