2 WEB_BROWSERS

       If  you  want  to  run xpdf automatically from netscape or
       mosaic (and probably other browsers) when you click  on  a
       link to a PDF file, you need to edit (or create) the files
       .mime.types and  .mailcap  in  your  home  directory.   In
       .mime.types add the line:

              application/pdf pdf

       In .mailcap add the lines:

              # Use xpdf to view PDF files.
              application/pdf; xpdf -q %s

       Make sure that xpdf is on your executable search path.

       When you click on a URL link in a PDF file, xpdf will exe-
       cute 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:

              urlCommand "netscape -remote 'openURL(%s)'"

                                                               ()

2 COMMANDS

       Xpdf's key and mouse bindings are user-configurable, using
       the bind and  unbind  options  in  the  config  file  (see
       xpdfrc(5)).   The bind command allows you to bind a key or
       mouse button to a sequence of one or more commands.

              End a selection.

              cal to followLink.

           bind Q              any         quit

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

           bind h any scrollLeft(16)
           bind l any scrollRight(16)
           bind k any scrollUp(16)
           bind j any scrollDown(16)

                                                               ()

2 REMOTE_SERVER_MODE

       Xpdf  can be started in remote server mode by specifying a
       server name (in addition to the file name  and  page  num-
       ber).  For example:

              xpdf -remote myServer file.pdf

       If  there is currently no xpdf running in server mode with
       the name 'myServer', a new xpdf window will be opened.  If
       another command:

              xpdf -remote myServer another.pdf 9

       is  issued,  a  new  copy  of  xpdf  will  not be started.
       Instead, the first xpdf (the server) will load another.pdf
       and display page nine.  If the file name is the same:

              xpdf -remote myServer another.pdf 4

       the xpdf server will simply display the specified page.

       The -raise option tells the server to raise its window; it
       can be specified with or without a file name and page num-
       ber.

       The  -quit option tells the server to close its window and
       exit.

                                                               ()

2 XIT_CODE

       The Xpdf tools use the following exit codes:

       0      No error.

       1      Error opening a PDF file.

       2      Error opening an output file.

       3      Error related to PDF permissions.

       99     Other error.

                                                               ()
