need to edit (or create) the files
.I .mime.types
and
.I .mailcap
in your home directory.  In
.I .mime.types
add the line:
.PP
.RS
application/pdf pdf
.RE

When you click on a URL link in a PDF file, xpdf will execute the
command specified by the urlCommand config file option, replacing an
occurrence of \'%s' with the URL.  For example, to call netscape with
the URL, add this line to your config file:
.PP
.RS
urlCommand "netscape -remote 'openURL(%s)'"
.RE
.SH COMMANDS
Xpdf's key and mouse bindings are user-configurable, using the bind and

Previous versions of xpdf included a "viKeys" X resource.  It is no
longer available, but the following bindings are equivalent:
.nf

    bind h any scrollLeft(16)

    bind k any scrollUp(16)
    bind j any scrollDown(16)

.fi
.SH "REMOTE SERVER MODE"
Xpdf can be started in remote server mode by specifying a server name
(in addition to the file name and page number).  For example:
.PP
.RS
xpdf -remote myServer file.pdf
.RE
.PP
If there is currently no xpdf running in server mode with the name
\'myServer', a new xpdf window will be opened.  If another command:
.PP
.RS
xpdf -remote myServer another.pdf 9
.RE
.PP
is issued, a new copy of xpdf will not be started.  Instead, the first
xpdf (the server) will load
.I another.pdf
and display page nine.  If the file name is the same:
.PP
.RS
xpdf -remote myServer another.pdf 4
.RE
.PP
the xpdf server will simply display the specified page.
.PP
The -raise option tells the server to raise its window; it can be
specified with or without a file name and page number.
.PP
The -quit option tells the server to close its window and exit.
.SH EXIT CODES
The Xpdf tools use the following exit codes:
.TP
0
No error.
.TP
1
Error opening a PDF file.
.TP
2
Error opening an output file.
.TP
3

.TP
