Well, tried the look-up function earlier today. Got an answer as expected. Very nice.
Tried again after reminding myself what the click pattern was under Settings in the phone app. Started playing music. Ooooh, double click and hold means click once then click again and don’t let up after the second click.
I’ll either get them straight in my head over some brief amount of time, depending on how often I do a search, or I’ll have to change the click settings.
Anyway, that works with some understandable user “error”.
