OK, so I have attempted to create a (:pageaction :) markup element, but I can't make it work. I'm enough of a noob to not understand what the problem is. I know that PageAction is being called because I stuck some debug strings in there and they were being displayed on the page. It just appears that setting the action to text is not working properly.<br>

Make sure you check your $action first to avoid an infinite redirect and also to still allow yourself to edit the page, use diagnostics, etc. If you want to get fancy you might want to look into (:pageaction browse=mynewaction print=myprint edit=myedit:) type of syntax which would allow mapping of various actions to other actions (take a look at the ParseArgs() function if you decide to try to implement this more generalized functionality). </div>
