Tab order and focus on input elements
During the flow of the conversation, keyboard focus should follow the editable elements in the input areas so that the person doesn’t have to keep moving their mouse and clicking in boxes as they go:
Start: [Enter your code here] has keyboard focus Then: [Enter your name here] has keyboard focus Then: [Yes] button has keyboard focus (so if I press space, I can select it) etc.
Also, set internal tab order on input areas. e.g., on “I want the name [x].gent [Send]”, the focus should start on the textbox and Tab should take you to the Send button.
