The doClick JavaScript routine generated by Domino chains together an OpenDocument and the Action URL with a &Click= parameter. I imagine this means to tell Domino to act as if the second URL had been clicked but I couldn’t find this documented anyplace. Can all Domino URLs be chained together like this?

As @formulas and script can only be executed on the server, if you use such e.g. in a button on a page, the page must be submitted to the server for the code to be executed after which the updated page is returned to the browser. The doClick parameter is used to tell the server why the page is being submitted i.e what action is required e.g
This tells the server to execute the code defined in a button in the body of the form.
So it only makes sense to set &click to something that points to some sort of form action (which as you can see from the above is best left to domino).
