How to let a user repeatedly click many buttons on same page?

I'd suggest you look at the Event Handler widget:  http://www.infosemantics.com.au/catalog/widgets/interactive/wdgt_event_handler_01

It will allow you to set up multiple instances of the widget (you need 20?) on the slide, each of which has a Success caption set to play a particular audio file when the button is clicked.  You can also use widget event to trigger an Advanced Action that will unhide the image you want to show at the same time.

Set the widget Preferences to Disable Continue and Reset Success/Failure after Action.  This will mean that your user will remain on the same slide clicking happily away for as long as they like.

Set up another button or widget with the Success action set to jump to your quiz as the means to exit the slide.

Hello,

You could attach the audio to the Image that will be made visible when the user clicks on a button. But you also have to be sure that the playhead doesn't continue. Clicking on a button normally releases the playhead and it will continue on the slide. So I suppose you will have to create advanced actions to be triggered by the button, in which you:

• show the image (and audio will play)
• rewind the playhead by the Expression   rdcmndGotFrameAndResume = rdinfoCurrentFrame - 1

Each button will need its proper Advanced action, because every image has its porper ID. But you can easily duplicate the first Advanced action, and the only thing to be edited is the ID of the image.

If this is sounding like Chinese, sorry. In my blog I have been trying to give some introduction and explain usecases for variables/advanced actions. Sometimes they will point to a longer article. If you are totally new to variables (like the 'rd' ones above), you could have a look at those two posts:

Use variables without advanced actions

Unleash power of variables with advanced actions

Both are pointing to articles.
