yes, I can use it for some other action/menu in Photoshop. My problem is that it hides a keyboard shortcut I have set in macOS (open a notes app). And that as long as I am inside Photoshop that keyboard shortcut does not work. I want to be able to remove that shortcut from Photoshop completely. Assigning it to another action would still hide my global shortcut.
Sure, I could change my shortcut. But I am using it now for many years, and I really think an application like Photoshop should not grab a shortcut from me ;-)
