I am redesigning my website and I began implementing the accesskeys, using numbers instead of letters, to avoid conflicts as described here:

Accesskeys and Reserved Keystroke Combinations http://www.wats.ca/resources/accesskeysandkeystrokes/38

But later I discovered that using numbers for accesskeys is not the solution:

More reasons why we don't use accesskeys (accesskeyconflicts) http://www.wats.ca/articles/accesskeyconflicts/37

And after all, I was confronted with the solution below:
Link Relationships as an Alternative to Accesskeys http://www.wats.ca/articles/accesskeyalternatives/52

But I am still not satisfied.

Therefore, I still want to use them.

So while I would like to improve my Access Keys functionality, I would like to ask here, what do you think about this code example?

Your opinion or comments would be warmly appreciated.
