I just wanted to say that layout-wise, it should be more clear that
there is an important definition there. E.g. by putting it in the
definitions section.

To sum up, it's semantically gesture-specific, but protocol-wise it's
not. IMO Peter's wording is fine.

Henrik and Peter said what I wanted to address here - no need to restate.
