the docs. However, I'll present a *very basic* step-by-step:
1. go to Setup->Armatures
2. click New Armature
3. activate Realtime Draw
4. click in the world view to add a handle, then deactivate
> 5. in the Handle block, click on the handle in preview area and
6. in the Action block above, choose Type->Click & Add Action-
7. click the [+] button to add the action to the handle you just
8. in the Command block below, choose the desired command
Go to KeyCommand Manager
Set class to Command
Name the command "Upper IK Chain"
enter the command as you would int he command line
click the "+" key
When you go back to setup mode -> Armature
"Upper IK Chain" will be listed and you just assign...viola!
THIS is so FUC&!ng Sweet!
