I have an old list but it should be updated. Could be a great resources if 
it was.

Anyway, in the case of Alt+left it didn't appear the grid really meant to 
use it. Better to check always the modifier key and let it go if it's not 
the key you're looking for.

Reserved keystrokes for borwsers and operating system functions






Aaron,
Is there a list of key combinations that ARIA (Web 2.0) applications 
should never use?

There are already some conflicts in the best practices, in that case the 
best practices says the Widget should win.

Are these combinations going to be OS and browser specific?

Jon
