I did not know this until I searched for it:

Quote: If your figure uses a standard T-position pose, and also is grouped similarly to the standard Poser figures, you can use the Hierarchy Editor to assign standard rotation orders to the joints in your figure. This can save time in setting up the joint rotations. You can learn more about configuring rotation orders manually in Setting Joint Orders .

To apply standard rotation to a figure:

Choose Window > Hierarchy Editor to display the Hierarchy Editor. Select the Universe. Click the Apply Std Rotation Order button to apply the standard rotation settings. © 2020-2021 Bondware, Inc. Last updated February 25, 2021 Unquote

That is very useful for T-posed figures.

I am sorry, my browser refuses to allow me to apply a hyper link.

Ahhh worth reading the manual as I also found this nugget:

"You can also use curve bends instead of the normal twist/joint/ joint bends. When you set up a joint using curves, the joint will have one twist and one curve primitive. The curve primitive will automatically bend the body part as if that part were part of a curved chain of objects. This feature is very handy for body parts such as tails or antennae.
