First of all, it's not an Emacs bug, so I'm closing this before
getting started to work on emacs-w3m (and I'll report it here in
short when I'm able to make emacs-w3m something better).

Currently `w3m-imitate-widget-button' will work only in the body
area that emacs-w3m renders.  There tab and backtab keys are
bound to `w3m-next-anchor' and `w3m-previous-anchor' that behave
like `forward-button' and `backward-button' if evaluating the
value of `w3m-imitate-widget-button' returns non-nil.

Thanks.
