How do i make my scroll buttons keep scrolling when pressed?

I have created two scroll buttons for my dynamic text field, following this guide

http://www.kirupa.com/developer/flash5/scrolltext.htm

My problem is, that you have to click the buttons many times to scroll down to the end.
How do you make it possible to “Press and hold” the mousebutton instead?

My code is as follows:

TextField name: scrollableText

Button Up Code:

on (press, release, keyPress "<Up>") {
    currentScroll = scrollableText.scroll;
    if (Number(currentScroll)>1) {
        scrollableText.scroll = currentScroll-1;
    }
}

Button Down Code:

on (press, release, keyPress "<Down>") {
    currentScroll = scrollableText.scroll;
    if (Number(currentScroll)<Number(scrollableText.maxscroll)) {
        scrollableText.scroll = Number(currentScroll)+1;
    }
}

Thanks in advance :slight_smile:
