A SKETCHY CDVI HELP FILE

Unfortunately, CDVI does not have on-line help, and the TeX file for the
printed documentation seems to be lost.  Here are the basic keystrokes
you might be looking for:

O -- Zoom out (to smaller magnification).  There are two reasons for
reducing magnification:  to bring more of the page into the field of view,
and to read some text in a font that is not available at the largest 
magnifications.

I -- Zoom in (magnify).

N or <enter> -- Next page.

P or <backspace> -- Previous page.

Cursor keys -- Navigate around the page in the obvious way.

C -- Move to the center of the page.

Q or <esc> -- Quit the program (respond with "y" to confirm).

CDVI is a 10-year-old DOS program, and it sometimes does not cooperate
with Windows/Netscape.  If it flashes up briefly and then disappears, try
exiting from Netscape and then reloading Netscape.  (As far as we know,
this problem starts whenever one tries to view a file using the "File"
menu of Netscape -- and persists until you kill the Netscape session.  
There is no problem as long as you stick to Web links.)
