I essentially need to achieve a screen with a graphic. Graphic has multiple highlight boxes. User clicks each highlight and a different feedback/caption box appears and remains on screen. When complete, user clicks a Next button to proceed.
Ideally I would like each feedback/caption box to disappear/reappear each time a highlight box is clicked, but I'm not sure if that's too time consuming.
I'm after the easiest way to achieve this 
My approach would be this;
- Replace the duo highlight box + transparent by a shape button with the look of a highlight box. Why two object when one can do the trick? Moreover a shape button can have any form whereas a highlight box is always rectangular. Have all the shape buttons pausing at the same time.
- Create the feedback text containers and hide them in output, will label them Tx_one, Tx_two.....
- Group the feedback texts in Gr_Text
- Create a shared action that will be triggered by the Success event of each shape button:
- Hide Gr_Text the group (bold) will be a parameter
- Show Tx_one the text container will be a parameter
- Apply this shared action to each shape button and choose the right parameter. The first will always be the same, only the second one will have to change
That shared action can be reused on each slide where you want to have a similar set up (group will need another name, each name has to be unique). Shared actions can easily be used in other projects as well.
