RE: Reserved keystrokes for borwsers and operating system functions

The battle between widgets and browser access to the keyboard is why the
AXS library developed by Chris Blouch on my team now uses
Alt+Control+the letter key.
 
To be honest, I'm not sure how the keyboard battle is resolved if there
isn't some path toward better cooperation between the widget and
browser. My company develops web apps that in many cases replace
software applications. I suspect consumers want the same or equivalent
behaviors when they're accessing email via a webmail app. Hopefully this
issue will spark greater participation in the DHTML Style Guide working
group that meets weekly on Tuesdays at noon. You can see the
widget-specific keyboard behaviors discussed thus far at:

I have an old list but it should be updated. Could be a great resources
if it was. 
http://www.mozilla.org/access/keyboard/ 

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
