I have re-useable master files for my lessons. Coloured rectangles hide the answers.

The rectangles can be removed by clicking and deleting . That works, but is time-consuming and awkward when standing at the screen, especially when I have 10 of them on the one page and I'm trying to hit that little red cross in the toolbar! With the boxes removed though, I can save the file as a pdf for my students where they can see the answers.

I recently discovered the "object animation" feature. This lets me set up boxes which disappear from the screen when you click on them. The students love it, and it looks much more professional. BUT the boxes reappear when I save as a pdf for the students!

Is it possible to include a fade & delete option in the object animation menu?? I'm sure this would be very useful for many teachers.

Thank you!
