[Commentor] LC-302 Ian Jacobs [Comment] * Access key support on traditional desktop devices is problematic at best. I do not know about the current state of support from the WCAG WG for access keys (looking in the WCAG 2.0 techniques, I find only a placeholder). Is access key support on mobile devices expected to be more interoperable? [Commentor reply] yes [Working Group decision] 
Yes, access key support on mobile devices is interoperable among mobile devices and with some desktop implementations.
