Grid-cell keyboard movement: Home unexpectedly jumps to the first grid row · case 02
Home unexpectedly jumps to the first grid row.
Case contract
Arrow keys move one cell and clamp without wrapping; Home/End target row edges; Control additionally targets the first/last row.
Why this case matters
A deterministic model of grid-cell keyboard movement; this isolates one interface invariant without requiring a browser.
One recorded failure
