Thanks Laura, you keep me honest (

I think 'trigger' was the word I'd intended, that's updated in the preview again.

    Hi Alastair,
    Thank you for your work on this. Nice job. Great illustrations.
    I think you may be missing a verb in then last sentence. It currently
    reads "in a similar way would not the same browser behaviour."
    Maybe something like: "in a similar way would not PROVIDE the same
    browser behavior." could work.
    In addition "behavior" would be the American English spelling for behaviour.
    Thanks again.
    Kind Regards,
