Denotes a formal term whose meaning is defined in the Glossary.
When this font is used, the Glossary definition takes precedence
over normal English usage.
Sometimes a glossary term appears subscripted,
as in "whitespace2."
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.
Denotes the introduction of a formal term locally to the current text.
There is still a corresponding glossary entry, and is formally equivalent
to a use of "name," but the hope is that making such uses
conspicuous will save the reader a trip to the glossary in some cases.
Denotes a symbol in the common-lisp package.
For information about case conventions,
see Section 184.108.40.206.1 Case in Symbols.
Denotes a sample name or piece of code that a programmer
might write in Common Lisp.
This font is also used for certain standardized names that are not
names of external symbols of the common-lisp package,
such as keywords1,
and loop keywords.
Denotes the name of a parameter or value.
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.
