no, there is no good reference anywhere.
m$ has some docs but they are build with IIS in mind so they have nothing much to offer.

basically, you don't need to click on anything.
with xmlhttp, you can code your own web-browser.

as to, if there is html-tag that wants to you click, you can see the source what the click does and do it in your script.

thus, xmlhttp is better for automation but just like you, ppl don't know much about it.
