Video attributes can be combined with a character argument passed to
\fBaddch\fR or related functions by logical-ORing them into the character.
(Thus, text, including attributes, can be copied from one place to another
-using \fBinch\fR and \fBaddch\fR.) See the \fBcurs_attr\fR(3X) page for
+using \fBinch\fR(3X) and \fBaddch\fR.) See the \fBcurs_attr\fR(3X) page for
values of predefined video attribute constants that can be usefully OR'ed
into characters.

The \fBechochar\fR and \fBwechochar\fR routines are equivalent to a call to
-\fBaddch\fR followed by a call to \fBrefresh\fR, or a call to \fBwaddch\fR
+\fBaddch\fR followed by a call to \fBrefresh\fR(3X), or a call to \fBwaddch\fR
followed by a call to \fBwrefresh\fR. The knowledge that only a single
character is being output is used and, for non-control characters, a
considerable performance gain may be seen by using these routines instead of
