/* Re: Right Shift
 *
 * Per a conversation I had on reddit with Rozakiin, matrix positions K312,
 * K313 and K314 are never in use all together at the same time.
 *
 * A 2.75u-sized right Shift uses position K313, rendering K312 and K314
 * inaccessible.
 *
 * A split right Shift, in either 1.75u/1u or 1u/1.75u (JIS layout) uses
 * positions K312 and K314, rendering K313 inaccessible.
 *
 *                                                            - @noroadsleft
