I don't know yet either.  As of now it would have to be a function that
pays attention to a `display-buffer' property at point.  That property
would, by default, act like the action argument of `display-buffer',
that is, specify what clicking at the button would do.  The function
would be used to override that - maybe overriding a regexp based alist
entry as well.  Just that we cannot well expect that a user will write
that function entirely from scratch so we probably should provide some
prespecified alternative here.

I see.  "s" didn't exist at the time `help-window-select' was added.
