Manage "enter-key" in SL 1
I would like to create a course where objects could be selected with the keyboard. I know that SL 1 allows to trigger an object if user press the "enter key". Bu I have some questions.
1. Is it possibile to let only specific objects clickable? At the moment if the learner uses the tab key he/she jumps to all object present in my slide.
2. if an object call a lightbox, how can i close this lightbox using only the keyboard? The X above at the right isn't clickable.
Thank you in advance.
