Regarding my recent inquiry as to how I could assign a keyboard shortcut to keyframe in Carrara 5 Pro: "Hello, Sorry it is not possible to assign a shortcut for this action. I filed a bug report for this issue and someone will look into it as soon as possible. Thank you for reporting. Best regards, Pierre-Sylvain Desse" Carrara 6 Pro, anyone? ;-) Gotta say this, though - they responded with a message the same day. Can't say that about other 3D packages I own.
