According to Photoshop keyboard shortcuts page, the shortcut for "Select next layer down/up" is ALT+[ or ALT+] meaning it hasn't even been set up yet since the [ or ] defines the user changing it themselves manually. But when going to the actual keyboard shortcuts dialog menu in Photoshop, nowhere is the "Select next layer down/up" to be found. So how am I supposed to manually change it?
Regardless, does anyone know how I can manually change the shortcut for the Select Next/Previous Layer?
