What Peter is trying to say here is that, besides the *client-side* action
of causing the form to be submitted, the button also appears in the POST
data stream as a type=value pair, and therefore you should include a
dictionary entry for it in your name-data pairs.

In terms of your question, yes, submitting the data triggers the server-side
actions that process it.
