const PUNCTUATION_CODE_MAP: Record<string, string>;

Defined in: constants.ts:313

Maps KeyboardEvent.code values for punctuation keys to their canonical characters.

On macOS, holding the Option (Alt) key transforms punctuation keys into special characters (e.g., Option+Minus → en-dash '–'), causing event.key to differ from the expected character. However, event.code still reports the physical key (e.g., 'Minus'). This map enables falling back to event.code for punctuation keys, similar to the existing Key*/Digit* fallbacks for letters and digits.
