normalizeKeyName

function normalizeKeyName(key): string;

Defined in: constants.ts:252

Normalizes a key name from a KeyboardEvent or a hotkey: single letters become uppercase, and the space character becomes Space. Other names are returned as written, because key names are case-sensitive.

Turkish dotless ı stays ı. Its uppercase is ASCII I, the uppercase of i, so uppercasing it would merge two different letters.

Parameters#

key#

string

The key name to normalize

Returns#

string

The canonical key name

Example#

normalizeKeyName('a') // 'A'
normalizeKeyName('ı') // 'ı' (Turkish dotless i)
normalizeKeyName(' ') // 'Space'
normalizeKeyName('ArrowUp') // 'ArrowUp' (already canonical)
