PROOF(1)		    General Commands Manual		      PROOF(1)

NAME
       proof - troff output interpreter

SYNOPSIS
       proof [ -mmag ] [ -/nview ] [ -F	dir ] [	-d ] [ file ]

DESCRIPTION
       Proof reads intermediate	language from file or standard input and simu-
       lates the resulting pages on the	screen.

       After a page of text is displayed, proof	pauses for a command from  the
       keyboard.  The typed commands are:

       newline	 Go on to next page of text.

       -	 Go back to the	previous page.

       q	 Quit.

       pn	 Print	page  n.   An  out-of-bounds page number means the end
		 nearer	to that	number;	a missing  number  means  the  current
		 page; a signed	number means an	offset to the current page.

       n	 Same as pn.

       c	 Clear the screen, then	wait for another command.

       mmag	 Change	 the  magnification  at	 which	the output is printed.
		 Normally it is	printed	with magnification .9; mag=.5  shrinks
		 it to half size; mag=2	doubles	the size.

       xval	 Move  everything val screen pixels to the right (left,	if val
		 is negative).

       yval	 Move everything val screen pixels down	(up, if	val  is	 nega-
		 tive).

       /nview	 Split	the  window  into nview	pieces.	 The current page goes
		 into the rightmost, bottommost	piece, and previous pages  are
		 shown in the other pieces.

       -F dir	 Use dir for fonts instead of /lib/font/bit.

       d	 Toggle	the debug flag.

       These  commands are also	available, under slightly different form, from
       a menu on button	3.  The	pan menu item allows arbitrary positioning  of
       the page: after selecting pan, press the	mouse button again and hold it
       down while moving the page to the desired location.  The	page  will  be
       redisplayed  in its entirety when the button is released.  Mouse	button
       1 also pans, without the	need for selecting from	a menu.

       The m, x, y, F, /, and d	commands are also available  as	 command  line
       options.
