Function describe_state 

pub fn describe_state(node: &AccessNode) -> String

Value + state, without name or role — confirms the result of activating or adjusting a control (e.g. “checked”) without re-reading the whole label. The item the keyboard is on inside it (its active_descendant, such as an open combo box’s highlighted option) is read first, so moving through a list reads each item while focus stays put.
