binding double-mouse-1 instead of mouse-2

[Raj Manandhar]

How can I customize modes such as Info or dired to use a double-click
instead of the middle button to jump to the node or file under the
mouse? I tried

(define-key Info-mode-map  [double-mouse-1] 'Info-mouse-follow-nearest-node)

but that has no effect. I think that the mouse-drag-region function in
mouse.el (which is bound to down-mouse-1) is swallowing the
double-click.
