Hi,
I'd like to remind about an useful new feature in PTE AV Studio 11 Pro - Quick Style.
See the Main menu > Slide menu.
Quick Style allows you easily copy animation from one slide to one or several other slides, keeping their original order, synchronization to soundtrack, and transition.
You can create and apply Quick Style with a shortcut keys (Shift + Ctrl + N and Shift + Ctrl + Q accordingly).
