        // TODO: handle pageDown and pageUp keys when scrolling through results

        // TODO: general cleanup and refactoring, commenting
        // TODO: detailed Exception handling, logging
        // TODO: FF2, up arrow from bottom has erratic scroll behavior (if multiple flexboxes on page)
        // TODO: FF2 (and maybe IE7): if maxVisibleRows == number of returned rows, height is a bit off (maybe set to auto?)
        // TODO: escape key only works from input box (this might be okay)
        // TODO: make .getJSON parameters (object and callback function) configurable (e.g. when calling yahoo image search)
        // TODO: escape key reverts to previous value (FF only?) (is this a good thing?)

        // TEST: allow client-side paging (return all data initially, set paging:{pageSize:#}, and ensure maxCacheBytes is > 0)
        // TEST: accept json object as first parameter to flexbox instead of page source, and have it work like a combobox
        // TEST: implement no results template
        // TEST: implement noResultsText and class
        // TEST: watermark color should be configurable (and so should default input color)
        // TEST: exception handling and alerts for common mistakes
        // TEST: first example should use defaults ONLY
        // TEST: add property initialValue, so you can set it when the flexbox loads
        // TEST: handle hidden input value for form submissions
        // TEST: how can we allow programmatically setting the field value (and therefore hidden value).  add jquery function?
        // TEST: use pageSize parameter as threshold to switch from no paging to paging based on results
        // TEST: if you type in an input value that matches the html, it might display html code (try typing "class" in the input box)
