Shortcuts To Adjustment Layers
Here’s another keyboard shortcut change that’s very useful if you use adjustment layers all the time. Go to Edit>Keyboard Shortcuts, choose Application Menus in the Shortcuts For drop-down menu, and twirl open the Layer option. Scroll down to New Adjustment Layer and click on one of the adjustments; for example, Curves. Change the shortcut to Command-M (PC: Ctrl-M) and accept that change. Now pressing that shortcut will add a Curves adjustment layer.
