Re: Multi selectable combo boxes

When you say most, are you referring to simulated constructs like an ARIA combobox or ARIA listbox, or a native select element that has multiselect enabled?

The ARIA listbox widget doesn't require the use of the control key, see "Example 2: Multi-Select Listbox"
https://www.w3.org/WAI/ARIA/apg/patterns/listbox/examples/listbox-rearrangeable/

When implementing an ARIA combobox that generates a listbox, the same rules apply for that widget type, so control would still not be required.

Yes, if you have a non-standard control that uses unexpected keystrokes, discoverability will definitely be an issue, so that by itself would likely fail a WCAG criteria for that purpose.

All the best,
