Page up/down was using pageSize instead of visibleRows (pageSize-1), moving one row too far per page. Additionally, ensureCursorVisible() was snapping the cursor to the viewport edge after paging, losing the user's relative position. Now both cursor and scrollOffset move together by visibleRows, and the same fix is applied to thread view paging. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Cover the thread view paging code path in keys.go with table-driven tests for page down and page up, including empty and small thread edge cases. Addresses review finding about missing thread view test coverage. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
