He was only printingon a garden-variety daisy wheel printer, for which inserting a pagebreak is a simple matter: just add a formfeed character, CTRL-l. But CTRL-l already means something to Emacs (&quot;redraw thescreen&quot;). How do you get the character into your file, without Emacsthinking that you're typing a command?</P><PCLASS="para">Simple. Precede CTRL-l with the &quot;quoting&quot; command,CTRL-q. CTRL-q tells Emacs that the next character youtype is text, not a part of some command. So the sequence CTRL-q&nbsp;CTRL-l inserts the character CTRL-linto your file; you'llsee <CODECLASS="literal">^L</CODE> on your screen. (Note that this represents a singlecharacter, instead of two characters.) In turn,when you print the file on a daisy wheel printer, the CTRL-l willcause a page eject at the appropriate point.</P><PCLASS="para">You can use this technique to get any &quot;control character&quot; intoan Emacs file. In fact, under pressure I've done some prettybizarre binary editing&nbsp;- not a task I'd recommend, but certainly onethat's possible.</P><DIVCLASS="sect1info"><PCLASS="SECT1INFO">- <SPANCLASS="authorinitials">ML</SPAN></P></DIV></DIV><DIVCLASS="htmlnav"><P></P><HRALIGN="LEFT"WIDTH="515"TITLE="footer"><TABLEWIDTH="515"BORDER="0"CELLSPACING="0"CELLPADDING="0"><TR><TDALIGN="LEFT"VALIGN="TOP"WIDTH="172"><ACLASS="SECT1"HREF="ch32_09.htm"TITLE="32.9 Unset PWD Before Using Emacs "><IMGSRC="gifs/txtpreva.gif"SRC="gifs/txtpreva.gif"ALT="Previous: 32.9 Unset PWD Before Using Emacs "BORDER="0"></A></TD><TDALIGN="CENTER"VALIGN="TOP"WIDTH="171"><ACLASS="book"HREF="index.htm"TITLE="UNIX Power Tools"><IMGSRC="gifs/txthome.gif"SRC="gifs/txthome.gif"ALT="UNIX Power Tools"BORDER="0"></A></TD><TDALIGN="RIGHT"VALIGN="TOP"WIDTH="172"><ACLASS="SECT1"HREF="ch32_11.htm"TITLE="32.11 Using Word Abbreviation Mode "><IMGSRC="gifs/txtnexta.gif"SRC="gifs/txtnexta.gif"ALT="Next: 32.11 Using Word Abbreviation Mode "BORDER="0"></A></TD></TR><TR><TDALIGN="LEFT"VALIGN="TOP"WIDTH="172">32.9 Unset PWD Before Using Emacs </TD><TDALIGN="CENTER"VALIGN="TOP"WIDTH="171"><ACLASS="index"HREF="index/idx_0.htm"TITLE="Book Index"><IMGSRC="gifs/index.gif"SRC="gifs/index.gif"ALT="Book Index"BORDER="0"></A></TD><TDALIGN="RIGHT"VALIGN="TOP"WIDTH="172">32.11 Using Word Abbreviation Mode </TD></TR></TABLE><HRALIGN="LEFT"WIDTH="515"TITLE="footer"><IMGSRC="gifs/smnavbar.gif"SRC="gifs/smnavbar.gif"USEMAP="#map"BORDER="0"ALT="The UNIX CD Bookshelf Navigation"><MAPNAME="map"><AREASHAPE="RECT"COORDS="0,0,73,21"HREF="../index.htm"ALT="The UNIX CD Bookshelf"><AREASHAPE="RECT"COORDS="74,0,163,21"HREF="index.htm"ALT="UNIX Power Tools"><AREASHAPE="RECT"COORDS="164,0,257,21"HREF="../unixnut/index.htm"ALT="UNIX in a Nutshell"><AREASHAPE="RECT"COORDS="258,0,321,21"HREF="../vi/index.htm"ALT="Learning the vi Editor"><AREASHAPE="RECT"COORDS="322,0,378,21"HREF="../sedawk/index.htm"ALT="sed &amp; awk"><AREASHAPE="RECT"COORDS="379,0,438,21"HREF="../ksh/index.htm"ALT="Learning the Korn Shell"><AREASHAPE="RECT"COORDS="439,0,514,21"HREF="../lrnunix/index.htm"ALT="Learning the UNIX Operating System"></MAP></DIV></BODY></HTML>
