Add PrtSc to the numpad, filling the nav block
Between Del and PgDn, which makes the nav block a solid 3x2 and leaves the arrows isolated by a symmetric pair of gaps rather than three asymmetric ones. 26 keys. PrtSc earns a key because it is the screenshot key on every Linux desktop; Insert, ScrLk and Pause stay on a layer. Co-Authored-By: Claude Opus 5 <[email protected]>
