+/**
+ * Used to match key events for any keyboard layout, especially on Windows and Linux,
+ * where non-latin character with modified (CMD) is not substituted with latin-based alternative.
+ *
+ * Uses `event.key` when it's latin, otherwise fallbacks to `event.code` (if mapping exists).
+ *
+ * Example of pressing "z" on different layouts, with the chosen key or code highlighted in []:
+ *
+ * Layout                | Code  | Key | Comment
+ * --------------------- | ----- | --- | -------
+ * U.S.                  |  KeyZ  | [z] |
+ * Czech                 |  KeyY  | [z] |
+ * Turkish               |  KeyN  | [z] |
+ * French                |  KeyW  | [z] |
+ * Macedonian            | [KeyZ] |  з  | z with cmd; з is Cyrillic equivalent of z
+ * Russian               | [KeyZ] |  я  | z with cmd
+ * Serbian               | [KeyZ] |  ѕ  | z with cmd
+ * Greek                 | [KeyZ] |  ζ  | z with cmd; also ζ is Greek equivalent of z
+ * Hebrew                | [KeyZ] |  ז  | z with cmd; also ז is Hebrew equivalent of z
+ * Pinyin - Simplified   |  KeyZ  | [z] | due to IME
+ * Cangije - Traditional | [KeyZ] |  重 | z with cmd
+ * Japanese              | [KeyZ] |  つ | z with cmd
+ * 2-Set Korean          | [KeyZ] |  ㅋ | z with cmd
