Yes, a loop could be used (though in that case I wouldn't suggest working with selections) but, as I also said, VBA has no idea what a grammatical sentence is. For example, consider the following:

Mr. Smith spent $1,234.56 at Dr. John's Grocery Store, to buy: 10.25kg of potatoes; 10kg of avocados; and 15.1kg of Mrs. Green's Mt. Pleasant macadamia nuts.

For you and me, that would count as one sentence; for VBA it counts as 5... Consequently, the VBA 'shuffle' would treat it as 5 sentences that would each be shuffled only within that VBA 'sentence' range.
