Hi Dave, Thanks for reading things over. I think the word "may" reflects the complexity of this. For example: - a user agent may decide to respect access keys in the content above its own user interface keyboard commands. - the user agent may not know what type of keyboard is available (e.g. on a cell phone) - the user agent may not know what keys the operating environment will take.
