Hi,
This what does this statement do?

var groupNames = jQuery(">tbody>tr.jqgroup span[title]", grid);

p.s. I have no other information, sample code, or demos, just this line.  If that is not enough, please allow someone else to answer.

"grid" would be another jquery object that you're passing in.  Presumably a table element.
The jquery will select:

all spans that have a title attribute, anywhere within rows that have a jqgroup class, that are direct children of a tbody element, that's a direct child of the passed in grid.

Brief example of the above:

    <table id="mainObject">
        <thead>
            <tr class="jqgroup">
                <th><span title="blah">won't match, not within tbody</span></th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td><span title="blah">won't match, row doesn't have a jqgroup class</span></td>
            </tr>
            <tr class="jqgroup">
                <td>
                    <span>won't match, no title attribute</span>
                    <span title="blah">will match, has all criteria</span>
                </td>
            </tr>
        </tbody>
    </table>

Thanks, what is the leading >?

Also, why not use a
grid.find()
or
grid.children()

The leading > just means direct child of the "grid" you're passing in.
In this case, I can only assume it would be to not select child tables inside of that one.  But just a hunch.

And not really any difference.  If I were doing it I probably would have used .find().
.children() would be different, as that will ONLY select direct children.
