also I might have caused some misunderstanding.
The correct procedure i mean is:
- selecting a builder
- pressing w
- releasing w
- holding alt+shift
- dragging over mexes
- releasing alt+shift
this way I area mex with 2 solars (or wind gens) and my question was to add defensive structures to this "macro" or one def structure to the ctrl+shift macro for only one energy building.
hope it now more understandable...
