Howto ReUse NLA Actions using Python

Coding Python Support
1

I am facing a problem.
I created 4 Bones with 2 NLA Actions.

  1. goRight for 20 Frames
  2. goDown for 20 Frames
    In the File www.patricia3d.com/avis/test1.blend
    When you run the python script ( included ) it shows 2 actions.
    Now I want goRight on Frame 120 and 160 and goDown on Frame 100 and 140.
    Is there any way in Python automatically select actions and Paste on the required frame.
    Please help.
