Radio

One choice from a short list in a form: small round keys in a fieldset, the chosen one pressed with a printed dot.

Tab into the group once; the arrow keys move the choice.

• Group radios in a <fieldset> with a <legend>; screen readers then read “Channels, Mono, radio, 1 of 3”.
• One Tab stop for the group; arrows move the choice.
• For a machine’s mode or a view filter, the selector is the same radio group, drawn as latching keys.
