Forgot to mention that you will need to uncomment this code in bookmark+-1.el:

;;   (define-key bookmark-map (vector (list mouse-wheel-up-event))
;;     'bmkp-next-bookmark-this-buffer-repeat)
;;   (define-key bookmark-map (vector (list mouse-wheel-down-event))
;;     'bmkp-previous-bookmark-this-buffer-repeat)

> 2. Use C-x p RET at several places in a file to create some bookmarks.
> 3. Use C-x p <up> <up> <up>... (or <down> <down>...) to cycle 
> among the bookmarks.  You will see a message showing the position at 
> each bookmark visited.
> 
> 4. Now try C-x p followed by repeated mouse-wheel down or up 
> movements.  You should see the same movement to each bookmark
> in turn, and the same position messages.  With your code the wheel
> repetition does not work.  With the code I sent it does work.
> This is the `while' condition I sent (again):

>                      (event-modifiers repeat-repeat-char))))
