Toggle Instances Selectable With One Bindkey

Hello,

I am new to skill and my problem is as follows: in Layout, there is an Objects palette that contains the visible & selectable options for Shapes, Instances, Fluid Guardring, Mosaic, Pins, Vias, etc. I want to be able to toggle the Selectable checkbox of the “Instances” with the use of a single bindkey. Currently, I have two bind keys set to make it selectable and not selectable:

z bindkey: _pteHiObjectSetSelectability(dwindow(‘pteObjectPalette2) “Instances” nil)·

Shift+z bindkey: _pteHiObjectSetSelectability(dwindow(‘pteObjectPalette2) “Instances” t)

Any suggestions would be greatly appreciated.

 Thanks!
