The second set of Coda clips are for JFilterOutput. What the heck is JFilterOutput you ask? It is a class in the Joomla! framework that strings and text in various ways. The number one thing I use it for is to replace "&" (ampersands) with "&" by using JFilterOutput::ampReplace for valid XHTML.
There are other methods to this class that do things like stripping text of formatted and scripting code (JFilterOutput::cleanText) and making text strings URL safe (JFilterOutput::stringURLSafe).
