 .PP
 The routine \fBchgat\fR changes the attributes of a given number of characters
 starting at the current cursor location of \fBstdscr\fR.  It does not update
-the cursor and does not perform wrapping.  A character count of -1 or greater
+the cursor and does not perform wrapping.  A character count of \-1 or greater
 than the remaining window width means to change attributes all the way to the
 end of the current line.  The \fBwchgat\fR function generalizes this to any
 window; the \fBmvwchgat\fR function does a cursor move before acting.  In these
 functions, the color argument is a color-pair index (as in the first argument
 of \fIinit_pair\fR, see \fBcurs_color\fR(3X)).  The \fBopts\fR argument is not
 presently used, but is reserved for the future (leave it \fBNULL\fR).
-Note that changing the attributes does not imply
-that a subsequent \fBrefresh\fR will update the screen to match,
-since the character values are not modified.
-Use \fBtouchwin\fR to force the screen to match the updated attributes.
