Keyboard Review

A focused review of keyboard accessibility — the single most important interaction requirement. If keyboard doesn't work, screen readers don't work, switch devices don't work, and many motor-impaired users are completely blocked.

Process

Step 1: Tab Through Everything

Starting from the browser address bar, press Tab repeatedly through the entire page. Document:

• Unreachable elements — interactive items that Tab skips
• Wrong order — focus jumps to unexpected locations
• Invisible focus — focus moves but you can't see where it is
• Keyboard traps — focus enters a region and can't leave
