EditingCommand

Remarks

The vocabulary, not the keys. AppKit calls these selectors and routes them through doCommandBySelector:; this is the same idea with no reflection in it (ADR-002). Two controls answering the same verb is what stops a text box and a code editor from drifting into two different keyboards, which is exactly what they had done.

⚠ Shift is not in here. Extending the selection is orthogonal to every motion — MoveWordLeft with Shift held is the same verb against a different anchor — so doubling the enum would double every table and every switch to say one bit. A control reads Shift off the event.

⚠ And nothing is in here that neither control answers. transpose and yank are real AppKit verbs and are deliberately absent: an id in a table that no control implements is a menu entry that greys out forever, which is this codebase's commonest defect wearing a keyboard.
