Looking to hide all but one layer in Photoshop? I was about to start hiding numerous layers by single clicking them when I the thought occurred to me that there might be a keyboard shortcut available.
The method is simple: Use the > alt < button while clicking the eye icon of the layer you want to be visible.
The result: All other layers will dis-appear.
To Undo this (Command/CNTRL Z wont work) DO the same thing – > alt click the eye icon of the same layer. All your layers should re-appear.
I hope this Photoshop tip helps you in any of your graphic design endeavors.
