Anyone who is experienced with Photoshop will tell you just how much they rely on keyboard shortcuts day-to-day
Keyboard shortcuts will not only speed up your basic commands, but will also make the difficult tasks a little easier.
You can assign new keyboard shortcuts to your desired commands by going to Edit>Keyboard Shortcuts.
Begin by choosing either menus, panels or tools, and then click on their current shortcuts shown to edit them. New Sets can be saved using the middle icon by the top bar.
