Flipping Docs while trying to add Signatures

Hello. I was recently upgraded to a newer version of Adobe. In my old version I could use the "Ctrl Alt +" to flip docs quickly and then place signature. It is not letting me do that in this newer version. It is making me get out of the area where I can add a signature, flip the doc then go back and so on as I go through the document having to flip and sign each page. It is very time consuming! Does anyone know a fix or am I missing something?
