Accessibility/EditorBehaviourOnUserInput

Summary

The article is aimed to propose editor behaviour on user input when control elements are contained in editable area. Under control elements are considered either HTML controls or ARIA controls.

Suggestion

The main point is control element inside of editable area should behave as "normal" control, i.e. when it is not placed inside of editable are.

mouse interaction

Control behaviour is the same on mouse input. For example, if user clicks on combobox (HTML:select) then drop down list is appeared.

keyboard interaction

Control behaviour is the same on keyboard input when control is focused until action on key press can be performed. For example, if textbox (HTML:input) is focused then arrow keys moves through its text. If listbox (HTML:select) is focused then up/down arrow keys change selected item.

tab navigation

If control is focused then tab press should navigate to the next control within editable are or outside of editable area if there is no control inside of editable are
