RE: Not described in words

I had the good fortune to catch Gregg in DC.  I took advantage of circumstances to pester him unmercifully about 2.1.1...

SH> Why are games not valid?

Games are perfectly valid!  Which is why I was seeking clarification bout "operable through a keyboard interface without requiring specific timings for individual keystrokes".  Why should games (like Frogger or Pong or Tetris) fail 2.1.1 when they are keyboard accessible?

This Success Criteria is about *how* the keys are activated and not *when* -- so, as written, 2.1.1 does *not* automatically fail keyboard accessible games.

LGR> Consider auto repeat functionality on a keyboard key.

Auto repeat, like Sticky Keys, is a feature of the operating system -- and therefore not a problem that needs to be addressed by WCAG.  (Although it does come up for 508.)

BB> Why have that clause?

Gregg already provided a couple examples on the list.  What I find even more compelling is that the phrasing is necessary to ensure that a developer not integrate a Mouse-Keys-Like feature into a web application as a way to satisfy the requirement for keyboard accessibility.
