pub const ACCENTS: [(CommandId, &str, Option<u8>); 9];Expand description
The accent target a selection maps to, or None for selections that carry
no accent (an image/icon shape, a multi-selection, or a pin group — the
picker targets one role-bearing object).
The accent picker’s cells: “no accent” plus the eight numbered ones, in
the order they are drawn, each as the command that sets it — so
accent-3 on screen and accent-3 in a script name one colour, and a
picker cannot offer a tenth colour the registry cannot be told about.
