Navigation - Previous Button
I have a E-Learn with a slide that has several different layers. Ever time the learner is finished with the layer, I want the layer to hid so that they can go back to the main slide then select something different to open up a different layer of information.
My question is: When on a layer, Is there a way to customize the 'previous' button on the navigation slide to hide the layer when pressed so that the learner can go back to the main slide without having an additional "back button" trigger? And then when on the main slide, have the "previous" button to go to the actual previous slide ?
Right now, when viewing a layer, I have the previous button on the navigation bar going to the previous slide and the back button going to the main slide (i.e., hiding the layer), but apparently having the two different buttons going to two different places is very confusing. I dont want to just disable the previous button though just in case the learner is genuinely interested in reviewing the previous slide (not layer) again.
Any ideas?
Thanks,
Jackie
