Users may select multiple items in one of two ways:
To select multiple items that are together in the list, click the first item. Then hold the shift key down and click on the last item. This will highlight all of the items between the two items clicked. The user may now use the palette arrows to move all of these items together.
To select multiple items that are not together in the list, click the first item. Then hold the Ctrl key down and click on as many additional items as desired. This will cause all of the items clicked on to be highlighted and moved together when the palette arrow is clicked.
