So my question is, what's the equivalent in S2? And is there a list of these variables anywhere?
CLARIFICATION: What I mean is something you can stick in wherever you like in customized HTML overrides, and an example of how that would work if, for example, you wanted the alt tag on an image to change to reflect the user-specified name. The S2 manuals seem to be written solely for the benefit of people who are used to reading code reference manuals, and not easily understandable to ordinary liberal arts majors who happen to know HTML (like me).
