Currently, if you want to select a range of elements and have a custom multiDrag key enabled (like the 'meta' key for Apple users), you must press BOTH the custom dragKey AND the shift key to select a custom range of elements.
This is rather uncommon for Apple users. Eg in the Finder, you simply press SHIFT to select a range of elements, and you simply hold the CMD (=meta) key if you want to select multiple different elements.
