Is there a way to quickly deselect all but one selection after selecting all the contents of a layer?
For example, the layer I select the contents of contains multiple, tightly packed parts but I only need to select one of them. The layer is often hidden below many other layers so I cannot use the wand tool as it will end up making a selection based on the layers that are visible, which is often different from what I need.
The parts are always at least a few pixels apart so there will always be a distance between the selections. I am wondering if this could somehow allow me to quickly deselect the rest of the selections and keep only one part selecting?
I’m not sure how well this will work with the way your document is layered, but you might consider selecting each part individually using the Quick Selection or Object Selection tool (not the old Magic Wand tool) and converting each selection to a separate path, for two reasons. You would be able to quickly select a path or any combination of paths as needed, and instantly convert them to selections. And if you need to adjust an individual part outline, it might be faster to edit it as a path.
