HTML output accesskey duplicate

[Daniel Nagy]

Hello,

`texi2any --html' produces HTML which has one or sometimes two
headers/footers [0] [1]. When there are two, the HTML accesskey
attribute is duplicated, resulting in inconsistent behavior.

If there is only one accesskey attribute, in Firefox, when pressing
shift+alt+<key> on this[0] page results in opening the next page.
The accesskey for the next-link is `n', so press shift+alt+n .

When there are multiple, pressing the accesskey results in switching
focus between the two elements, like on this[1] page.

To ensure consistent behavior, I suggest to remove the accesskey
attribute from the footer.
This way the access key always opens the requested link.

Sorry, I cant write a patch for this myself because my Perl skills are lacking.

Here [2] is more information about the accesskey attribute.

Best,
Daniel
