Grid Navigation

The ability to navigate through grid or table-based layouts using keyboard controls and assistive technologies. Calendar applications commonly use grid layouts to display weeks and months, which present significant accessibility barriers for screen reader users. Problems include complex visual grid structures that are difficult to linearize for sequential reading, irregular spacing and blank areas that disrupt screen reader navigation patterns, and limited keyboard support for moving between cells. Accessible grid navigation requires proper ARIA grid roles, arrow key support for cell-to-cell movement, clear row and column headers, and the option to switch to alternative non-grid views such as list layouts.
