I'd like to know what access keys I can use for my site. Anyone know where I can find a list? Also, I understand that the UK has a standard. Is anyone familiar with a site that lists standard access keys for other countries (for example, Japan)?
The British or UK standard is actually the only standard that ever reached a certain popularity and is used throughout the world as the one standard. The default layout is
S - Skip navigation
1 - Home page
2 - What’s new
3 - Site map
4 - Search
5 - Frequently Asked Questions (FAQ)
6 - Help
7 - Complaints procedure
8 - Terms and conditions

Besides that, access keys can be a barrier in itself which is why some usability experts advise to not use them (search for John Foliot's arguments).
