 .SH NAME
 \fB@TABS@\fR \- set tabs on a terminal
 .SH SYNOPSIS
@@ -42,10 +59,14 @@ The \fB@TABS@\fP program clears and sets tab-stops on the terminal.
 This uses the terminfo \fIclear_all_tabs\fP and \fIset_tab\fP capabilities.
 If either is absent, \fB@TABS@\fP is unable to clear/set tab-stops.
 The terminal should be configured to use hard tabs, e.g.,
-.sp
-.RS
+.NS

-.RE
+.NE
+.PP
+Like \fB@CLEAR@\fR(1), \fB@TABS@\fR writes to the standard output.
+You can redirect the standard output to a file (which prevents
+\fB@TABS@\fR from actually changing the tabstops),
+and later \fBcat\fP the file to the screen, setting tabstops at that point.
