Probably <kbd> does not mean key combinations exactly but this
is is closest what we can get.
Original meaning of <kbd> is so fuzzy so it was never used
for its purpose. At least I never seen <kbd> in the wild.
So it is probably safe to redefine it for keystrokes purpose.
I doubt that changing its role will break anything.
Speaking about shortcut resolution in general.
Here is one practical implementation that we have:
First of all we have extended format for @accesskey:
accesskey="A" - Alt-A (on Windows)
accesskey="!A" - just press on 'A' key - that is for mnemonics.
accesskey="^A" - Ctrl+A key.
Resolution of accesskey happens using following algorithm
(a bit simplified):
dom::element t = window.elementInFocus();
while ( t )
dom::element at = findAccessKeyInThisAndDescendants(t, accesskey) ;
if( at && at.activateElement() ) return true; // handled
t = t.parent(); // go to parent
function findAccessKeyInThisAndDescendants(element, accesskey)
return element.select( "[accesskey='%s']", accesskey); // a.k.a.
As you may see such algorithm handles elements with duplicate
@accesskey attributes - it simply selects closest element to the
one that is in focus. checkForAccesskey is being called if
keyboard event was bubbled up unhandled.
This algorithm tested in real-life scenarios and applications.
I think this is best what we can get for HTML.
