Custom player tabs
I just have a quick question about player tabs. I have made 2 of my own tabs which jump to a lightbox slide when clicked, which brings up a navigation menu to take them elsewhere. However, I only want these 2 tabs to appear in about 80% of slides. (For example, we have pre-tests in our course and we don't want learners to be able to click our custom tabs to navigate elsewhere before or during the pre-test). I was wondering does anyone know hot to do this? I know how to disable the inbuilt tabs (menu, resources etc) by just going to slide properties on the slide and unchecking it. Is there a way of unchecking the custom tabs I've added?
