Thanks, Bobosaur... my question actually got answered via IM or I would have checked back sooner. Basically what I was trying to determine was the purpose of the "Add Keyframe" function is Poser automatically sets a keyframe the instant I alter anything within a numbered scene. In Max, I use splines to set up paths and the control points are keyed to timing, but they don't require an actual "keyed" frame to manipulate. The path steps are simply keyed to the key frames you set. Basically I'm just now taking a first look at the way Poser handles things. All of the dynamics are, of course, a funtion of time, so, there's no reason to not learn how Poser looks at timed sequence and interpolation, and very good reason to learn about it very well, even for still artists.
