Which functions for addressing specific forms in a page?

[Thorsten Jolitz <tjolitz@xxxxxxxxx>]

Hi, 

I want to write elisp code that presses specific buttons or links in a
webpage that I created - which w3m functions do I use for that?

Say I have a page with 5 buttons  A, B, ..., E, and want to write an
elisp function 

,----------------------------
| (defun press-button (label-or-number-or-so) ...)
`----------------------------

and bind it to a key, how do I do that using the emacs-w3m libraries?

Thanks for any hint.
