In Mathematica it's easy to Import
data from the web and perform all sort of Web Operations. But the later doesn't allow to simulate a more interactive browser operations, such as a "Click" action into a button or link. This may be relevant, for instance in in this question, where a follow-up comment asked for the "next page".
How can we open a web-page, click a particular button or link and extract relevant information such as the URL, page source and list of links of the new web-page?
