 .SH DESCRIPTION
 The
-.BI case
+.B case
 macro provides syntax which
-.B cppawk
+.I cppawk
 translates very directly to the GNU Awk
-.BI switch
+.B switch
 statement, or else to alternative code which works with other Awk implementations.
 
 The purpose of the macro is easy conversion of
-.BI switch
+.B switch
 code; therefore, it has the same semantics with regard to fall through between
 cases, requiring an explicit break.
 
 The clauses of
-.BI case
+.B case
 are labeled with the identifiers
-.BI of,
-.BI matching,
+.BR of ,
+.BR matching ,
 or
-.BI mixed
+.BR mixed ,
 which take arguments, and are followed by one or more statements. The last one
 of those statements must always be a
-.BI cbreak,
-.BI cfall
+.BR cbreak ,
+.B cfall
 or
-.BI cret
+.B cret
 statement, described below.
 
 Regular expression keys must use the
-.BI matching
+.B matching
 label; ordinary keys compared for equality must use the
-.BI of
+.B of
 label. The
-.BI mixed
+.B mixed
 label allows for both keys to be included in one case.
 
 The
-.BI of
+.B of
 and
-.BI matching
+.B matching
 macros take variable arguments. Multiple matching keys or regular expressions
 are specified as multiple arguments, rather than by repetition of the
 construct:
