Parameter syntax: [ preview_command ]?
Copies document being edited to a temporary file called __PREVIEW__document_name.html located in the same directory than the document and then executes its parameter if any, or by default:
"start %F" on Windows.
"(netscape -raise -remote "openFile(%F)" 1> /dev/null 2>&1) || (netscape "%U" &)" on Unix. This command assumes that Netscape 4 is installed on the machine running XXE.
Variable %F is substituted with preview file name and variable %U is substituted with preview file URL before the preview command is executed.
Example: use this parameter to start Mozilla (which happens to support the same command line options than Netscape 4):
(mozilla -raise -remote "openFile(%F)" 1> /dev/null 2>&1) || (mozilla "%U" &)
