In AutoCad 2004LT I have the need for a couple of custom buttons.
I have made an "ALL Layer OFF" & "ALL LAYER ON" toolbar using the following macro commands:
All Layers On^C^C-LAYER;ON;*;;
All Layers Off^C^C_ai_molc;\-layer;off;*;;;
 
What I want is for the All OFF button is to leave the default "Layer 0"
on. The all off button now , when clicked, you must click a layer object
and then all but that layer is turned off. I would like to have a button that turns on just "layer 0" or allows the current function I have plus leaves the "layer 0 " on.

You can just add "_-LAYER;_ON;0;;" at the end of the All Layers Off macro.
