Did MS include this option to use the split vertically?

Thanks

No, not quite like the horizontal split. But if you use the Window
New Window command and then Compare Side-by-Side, you get nearly the
same effect.

Thanks for the reply

As mentioned though, I want to use this on the *same* document, not
compare with a different document. This doesn't seem to be possible,
I can only compare with different documents.

The New Window command does give you a second window into the *same*
document, and the Compare command then uses both windows in the same
document. If you then want to look at different parts of the document in the
two windows, click the Synchronous Scrolling button on the floating toolbar
to turn it off.

Try it, you'll like it. :-)
