Thanks, GKDantas and Miss Nancy, or should I say, ,*,muito obrigado?"

O senhor, I haven't begun exploring the motion clips in Carrara 6, but as soon I read your comments, I realized that may well be what I need to do.  I can see this coming weekend will be spent in front of the computer with the manual open on another screen!

A senhora Nancy,* it is impossible to delete frames from a Carrara timeline, but as GKDantas suggests, moving the keyframes forward through time will usually do something very similar to deleting the frames themselves.

Thank you both, though -- this has been most helpful!

*Eu amo o Renderosity!

Ciao!*
