Labels

Chains, phrases, and instruments can each have an 8-character name, accessible by navigating right to the top of the page on Chain, Phrase or Instrument.

While on the name row: A+←→ moves the character cursor (wrapping across the 8 characters); A+↑↓ cycles through the character set. There's no lowercase here, unlike the Project screen's NAME field. B clears the whole name.

The name appears at the top-right of the parent screen when the cursor is on that item - e.g. the chain label shows on the Song screen when you hover over that chain's cell, and the phrase label shows on the Chain screen when the cursor is on that phrase slot, and next to the title on the item's own screen too.
