Hi Rich,
Thanks!
Are you saying that Sakai is using the same type of datepicker and you
think it might be a simple configuration for us to make this work? Or
just that, we might need to fix it in Sakai, and you would anticipate it
would be a relatively easy fix?
Cheers,
Neal

> THis demo allows typing over the date field. You need to use option
> onSHow = “button” when you call jQueryUI’s datepicker and then in
> keydown handler be sure that you disable arrow keys from grabbing a
> date if the calendar is closed.
> I’m sure this functionality could be built into Sakai’s widgit.

> I played around for a long time with jQueryUI trying to provide access
> directly to the calendar table, however things never seemed to work
> out correctly. The article referenced above was an aha moment for me
> - jQueryUI already has keyboard control, so why not use it! In a
> keydown handler I just grab the currently highlighted item via css
> class and extract the info then use the date picker's formatDate
> method to provide a consistent string which I send to a live region to
> be spoken by the screen reader.
> The date field is wrapped in a div with role=”application”; this
> allows arrow keys to be passed to the datepicker widgit more easily.
> You can type a date in the field, or just press one of the four arrows
> and hear the date change; press enter when done.
> The keyboard handler listens for control+arrows and updates live
> region with a date string (including day) which corresponds to the
> highlighted cell in calendar. Typically this live region would be
> hidden from sighted users.
> The other set of keys (bare arrow keys) are handled and simply trigger
> their corresponding control+arrow counterparts. This is done because
> Jaws, for some reason, always pops you out of the text field when
> control+up or control+down is pressed.
> I should do something when enter is pressed; right now nothing
> happens, so the user won’t know something got selected.
> I should hide the live region (message area).
