Show and hide layers

[Acorn]

Folks,
I would like to command 2 or more layers open at one time while commanding all other layers to close. I know I can command layers to close if I name specifically, but that could be a long string of text prone to errors. I was hoping there was a command to close all 'other' layers.
So, for instance the Syntax in 'Web Properties' - 'Link to...' - popuppen "layer2","layer3"; close "all other layers syntax?"
I will attempt to add a picture. The names of the layers are different in the picture.
Thanks for any assistance in advance,

Thev, you could check if the Tweak here (https://www.talkgraphics.com/showthr...121#post358121) is still valid.

If so, let us all know.
