To maintain accessibility consistency with normal HTML select comboboxes, we need the RadComboBox to support the Home and End keys to jump to the 1st and last item respectively.  Currently, it just moves the text cursor to the start/end of the textfield.

If the change can't be made globally, can a new property be set to control this behavior?
Ideally too, Page Up/Down can jump multiple items at a time.  Currently, it scrolls the page.

See a 2009 forum post too (from someone else):

I see the other keyboard shortcuts listed here:

Per Anton: The keyboard support is specification is implemented according to the article (https://www.w3.org/TR/2013/WD-wai-aria-practices-20130307/#combobox) which is why there is no support for these keys.

We would like to request these additional keys be supported anyway.
