Hopefully someone has a quick and easy answer for me.. I'm well versed in using Poser to create stills, but I need help with animations!  I'm using Poser Pro 2010.  The problem I keep encountering is I don't know how to lock limbs in place for X frames, then unlock them, so now the limb slooooooooooooooooooooowly moves to the position at the end of the animation starting at the very beginning.  For example, say I wanted to make a simple animation where someone raises their hand and waves, then raises their second hand and waves later in the animation. Now, they'll start raising both hands at the same time, but the first one will move way faster as the second one creeps to its position in the keyframes.

I'd appreciate help!
