some question on leg rigging

i am following a leg rig tutorial, there’s a mention of transform lock constraint for toes and foot control which i do not find in later version 2.49. is it still necessary or it is the same as transform constraint? When i copy a mirror pose it pasted the same pose, are these thing related?:spin:

Got a link to the tutorial? Maybe might be able to help you out better.

Also - How did you mirror a pose? That’s a new one to me…
