New info on EZ checks Keyboard for review

Hi everyone,

I added to the wiki with the changed for the Keyboard section of Easy
Checks.  it's here http://www.w3.org/WAI/EO/wiki/EZ_Keyboard_Edits and
there is a Comments setion at the bottom.  It's looking pretty good to me
in terms of text content but may need illustrations.

Thanks,
Sharron
