+These routines insert the character \fIch\fP before the character under the
+cursor.
+All characters to the right of the cursor are moved one space to the
 right, with the possibility of the rightmost character on the line being lost.
 The insertion operation does not change the cursor position.
 .SH RETURN VALUE
-All routines that return an integer return \fBERR\fR upon failure and OK (SVr4
-specifies only "an integer value other than \fBERR\fR") upon successful
-completion, unless otherwise noted in the preceding routine descriptions.

+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
 .SH NOTES
 These routines do not necessarily imply use of a hardware insert character
 feature.
