Thread:Project:Support desk/Force view source

I am trying to work with others to troubleshoot a problem related to character entity references inside a  element on a wiki. I have created a user subpage exhibiting this problem, and I want to create a link that displays the subpage's wikitext without encouraging the viewer to make inadvertent changes and save them through reflex. What's the parameter for "view source" even if the viewer has the privilege to edit a page? Neither action=source nor action=viewsource exists. I tried [//www.mediawiki.org/wiki/Manual:Parameters_to_index.php?action=raw action=raw], but that produced a download dialog box. I tried [//www.mediawiki.org/wiki/Manual:Parameters_to_index.php?action=raw&ctype=text/plain text/plain], but that too produced a download dialog box because  is not one of the allowed types.
