Inline code can be realised using the = switch described 
in
section 7.2.1 or the markdown 
backtick. In addition, it can use the mardown/Doxygen backtick 
(`) convention: a string that is delimited by backticks is 
considered code, provided:
Currently,‘Var` is typeset as a variable (italics) and other terms are typeset using a fixed-width code font.
In addition, compound terms in canonical notation (i.e.,
functor(,...args...) that can be 
parsed are first verified as a file-specification for
absolute_file_name/3 
and otherwise rendered as code.
