You have seen that \CONTEXT\ commands are preceded by a \tex{} (backslash). This
means that \tex{} has a special meaning to \CONTEXT. Aside from \tex{} there are
other characters that need special attention when you want them to appear in
verbatim mode or in text mode. \in{Table}[tab:specchars] gives an overview of
these special characters and what you have to type to produce them.

Other special characters have a meaning in typesetting mathematical expressions
and some can be used in math mode only (see \in{chapter}[formulas]).
