So it works the other way around in Poser. In DS you spin the dial and then "Freeze". In Poser you "Teach" the dial.

• Rotate the joint to what ever position you want to "Teach"
• Open the dependencies for that parameter {Like one of the rotate dials)
• Click [Start Teaching]
• Spin the master dial of the morph you want to teach.

If you're creating a keyed dependency you need to set the zero point as well. Keyed dependencies have a Graph displayed below the dependency window.

• Rotate the joint to zero USE THE DIAL ON THE DEPENDENCY EDITOR ONLY lest you accidentally add dependencies you don't want
• Dial the morph to zero
• click [Stop teaching]

Don't touch any thing but the morphs's dial while teaching is on. Any thing you move will become a dependency of that dial. You can select and delete unwanted dependencies in the list but if you applied a pose ... Oh yee ...
