HTML interaction...

[Simon Lord]

Ok, this is where I ask a question without exhausting all avenues to
discover the answer...

If I have RunRev load an html page, what options, if any, do I have to
communicating to elements in that page?

First, some structure to understand what I'm asking:

This is a stack—not a plugin and not a stack talking to a browser.
This is a stack with a web page rendered inside the stack.

Can I target div's with ID?

[God please say yes.]

If so, what keywords should I be reviewing in the x-talk language?
