Ah! There it is. (I think I maybe knew that once.)

I think it might be worth documenting this in the manual. Perhaps in
Section 20.5 Deleting and Rearranging Windows, which might be better
named "Deleting, Rearranging, and Resizing Windows".

Also a search for "resize" in the manual doesn't currently find this
section even though it is where the (keyboard-based) resizing commands are
documented.

On the other hand, this functionality is not something a user would
expect to have to look up in the manual. Resizing things on screen by
dragging a handle provided when placing the mouse cursor over their
boundary is a very commonplace, almost universal idiom; it would be nice
if Emacs could do this by default.
