We can toggle off the visibility of all but one layer with Alt+LMB on the layer’s visibility icon in the Layers panel, but there’s no keyboard shortcut for it.
I find myself using this command very often while doing certain things, like painting on top of a sketch layer to get an uncluttered view of my progress.
“Toggle Layer Visibility” has a keyboard shortcut.
Can we get a new one for “Toggle Solo Layer Visibility”? In my case, it would certainly speed me up and smooth out my workflow a bit.
