Joomla - 如何判断{{}}链接到哪个?

I've been tasked with updating a page on our Joomla-powered website. Finding the page is easy enough from the contents area, but the two sections I need to edit are not on the page. Instead I find two markers: {{2}} and {{3}}. My assumption are these are placeholders for modules, but I can't for the life of me find any modules that contain the content I need to edit.

Is there a way to figure out what these place holders point to?

Joomla version is 2.5.

The curly brackets {} are typical of a Joomla Content plugin, however, normally there is more inside the brackets which can give clues to what the plugin is.

If these tags are in an Article, then I would hazard a guess that a Content plugin using onContentPrepare is processing the article body and replacing their contents. The first step will be identifying the plugin, which in turn may lead to a component (under the Components menu).

If that doesn't help — as this question is about Joomla specific implementation details, you may get a better result if you, try asking on the Joomla Q&A StackExhange site
