Keyboard (No Exception)
All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, with no exceptions.
In plain language
This is the strictest version of the keyboard-access rule: absolutely everything on the site must work with a keyboard alone — no exceptions at all, not even for things like freehand drawing.
Why it matters
The regular keyboard rule allows a narrow exception for things that genuinely require tracing a path (like signing your name). This stricter version removes even that exception, guaranteeing full keyboard access to every single feature.
In practice
Fails this criterion
A drawing tool on the site only accepts mouse or touch input, with no keyboard way to draw or achieve the same result.
Meets this criterion
Every feature on the site, including complex tools, offers a full keyboard alternative — for example, a rich text editor where every formatting option has a keyboard shortcut.
Test it yourself
Try using the entire site with only a keyboard, including any complex or drawing-like tools. If anything genuinely can't be done without a mouse or touch, this criterion is failing.
