I hope this clears that up.  The Sun Java Guru brought up Alt-Tab -- which lead me to worry that the actual nature of my question was not conveyed.  I understand that Alt-Tab is an OS keystroke and not something a Java applet should have access to.  But I can't abide leaving questions directed at me unanswered, so indulge me while I close this out...

No.  Alt-Tab works okay for StickyKeys.

Nope, but that wasn't my question.

Great!  Then not having something like 1194.21(b) in WCAG 2.0 should not be a problem.  And the applicability of 1194.21(g) is even more remote than .21(b).
