     4 \chapter{Standard Isabelle symbols}\label{app:symbols}
     5 
     6 Isabelle supports an infinite number of non-ASCII symbols, which are
     7 represented in source text as \verb,\<,$name$\verb,>, (where $name$ may be any
     8 identifier).  It is left to front-end tools how these symbols are presented to
     9 the user.  The following predefined standard symbols are available by default
    10 for Isabelle document output; most of these are also supported by
    11 Proof~General when used together with the X-Symbol package.
    12 
    13 Any symbol (or plain ASCII character) may be prefixed by \verb,\<^sup>, for
    14 superscript and \verb,\<^sub>, for subscript; e.g.\ \verb,A\<^sup>\<star>, is
    15 presented in {\LaTeX} as \isa{A\isactrlsup{\isasymstar}}.  Most symbols (and
    16 all ASCII characters) may be printed in bold by prefixing \verb,\<^bold>,, as
    17 in \verb,\<^bold>\<alpha>, which is printed as
    18 \isa{\isactrlbold{\isasymalpha}}.  Note that super- and subscripts may
    19 \emph{not} be combined with bold style.

    22 preparation.
