Yes, you'll need to make your own control. I've done something similar
to this on http://labs.metacarta.com/osm/ : you click on the 'osm' tool,
and then you can click to see a list of features near your click. The
pieces are all in:

  http://labs.metacarta.com/osm/osmutils.js

You can see the Handler, Control, and Toolbar code there.
