The specification says:
If specified, the value must be an ordered set of unique space-separated tokens that are case-sensitive, each of which must be exactly one Unicode code point in length.
However, as far as I have tested, it doesn't seems to be the case. Firefox uses Alt + Shift + key
(in which case, case-sensitivity would be a problem because shift
is commonly used for caps). There is no difference at all if I enable or disable caps lock.
Do you know any browser/device/OS which is case sensitive with this attribute ? Can I use safely accesskey="A"
and accesskey="a"
without expecting a difference ?
