Auto IK in 2.5?

Is there any way to do auto IK in 2.5? I don’t know or want to spend the time doing every bone.

anybody have any ideas?

From this page:

  • Automatic IK

This option, in the Editing Buttons, “Armature” Panel, automatically assigns a temporary IK chain to any translated bone, giving the same effect as if the selected bone had been assigned Targetless IK. This chain then only propagates over the connected Bones of the grabbed one.

In 2.5, auto-IK is in the tool shelf, under ‘pose options’

thank you!
