There is now an option for enabling a virtual keyboard in the question editing panel. Test editors can enable the virtual keyboard for candidates for better accessibility.
The virtual keyboard options include a complete keyboard for included languages, special character keypad (Spanish only), and number pads. The keyboard languages currently include English, Turkish, Russian, Arabic (Beta), French, Italian, German, Spanish and Hebrew (Beta).
The selected virtual keyboard can be previewed at the bottom of the editing panel.
