All parameters are saved along with body part positions when you save a pose to the Library palette. To save a pose to the Library palette:
Open the Library palette.
Select the Pose category and your desired subcategory.
Click the + button at the bottom of the Library palette. The New Set dialog appears.
Enter a name for the pose in the Set Name field.
Check the Include Graphs option if your pose includes graphs.
If you only want to include specific body parts in the pose, check the Select Subset button at the bottom of the New Set dialog. Check only the parts you want to include in the pose. Then choose OK to return to the New Set dialog.
Choose OK to continue. You are asked if you want to include morph channels, body transformations, or scales in the saved pose. Scales is selected by default. After you choose your options, click OK.
The Save Frames dialog has two options:
Single Frame: Saves your currently selected frame as a still pose.
Multi-Frame Animation: Check this option to save an animated pose, and enter the start frame and end frame of the animation to save in your pose.
