let's say I have a scene with a ton of keyframes, and   I don't want them accidentally altered, which is remarkably easy to do while working in Poser. Thus,  I want them keyframes of everything to be locked in place, except what I unlock. Can I do this globally?

Here's the situation: I have an animation scene (it's just a figure talking and moving), and now I just need everything to stay exactly the same, while I add some upper extremity (arms, hands) and prop movement.  

I went looking for lock/unlock buttons by the key channels in the animation pallette...nada.

Figure>Lock figure won't work for this, and Object> lock actor would work, but that's a whole lot of work, locking all those actors one at a time.
Isn't there a global lock python script of something that I could apply, and then just unlock the few actors that I need to key?

thanks

Here's my old Lock Parts script.  I think it will do what you want.

An even older one:

I don't remember why I made two scripts .... the readmes
should tell what each does.

wow, Thanks a million, Ockham, that is just totally awesome!
I'm telling you in all seriousness, you have been so helpful on this project, when it turns a reward  (it will be monetized, if popular enuf... it's an ecard) I will not forget to do something concrete. Now, all I can do is gush thanks!

Holy cow!  THANK YOU, Ockham! I've been going NUTS on a particular scene with way to many parts.  This is great.  

This lock/unlock tool is very useful, thanks again!
Just gotta remember to exit the program before closing Poser down (or even saving the file, I think) , or it gets upset, finicky, crashy.             YMMV, of course.
