[Alexandre Loomis]

In Notation Reference 5.3.4 - the \tweak command, the sentence

"Tweaking a whole chord *does not do anything *since its music event only
acts as a container, and all layout objects are created from events inside
of the EventChord:"

is misleading or incorrect. In the example directly following the sentence,
it does do something, it affects the entire chord. A possible change to the
phrasing would be

"Tweaking a whole chord *may not have the expected effect* since its music
event only acts as a container, and all layout objects are created from
events inside of the EventChord:"
