Fonts are used in this document to convey information.
Sometimes a glossary term appears subscripted, as in ``whitespace.'' Such a notation selects one particular Glossary definition out of several, in this case the second. The subscript notation for Glossary terms is generally used where the context might be insufficient to disambiguate among the available definitions.
This font is also used for certain standardized names that are not names of external symbols of the COMMON-LISP package, such as keywords, package names, and loop keywords.
In some situations the notation ``<<name>>'' (i.e., the same font, but with surrounding ``angle brackets'') is used instead in order to provide better visual separation from surrounding characters. These ``angle brackets'' are metasyntactic, and never actually appear in program input or output.
