[Closed] CS interface scripting?

I’m trying to make my own “simpler” floater with the keys from the usual interface of the bipeds that I often use, I been able to made the setkey, create layer, delete layer, collapse etc… but I can’t find a way to script the “anchor left leg” ( and right ) and opening the mixer.
thanks in advance.

i.e. To open the workbench I just assigned a button “open workbench” to the script
bipworkbench.open()
