| * <li> Regular character key for twelvekeys layout. |
| * <li> Function key for twelvekeys layout. |
| * <li> Circular highlight for twelvekeys representing "center" flicking. |

| * <li> Regular character key for qwerty. |
| * <li> Function key for qwerty. |
| * <li> Function key with "light" mark at top-right corner, for alt key on qwerty layout. |
| * </ul> |
| * |
| * The highlight design is: |
| * <ul> |
| * <li> put a circle highlight with inner shadow for just pressing a key. |
| * <li> put a triangle highlight with inner shadow for some directions. |
