In fact, a recent study in the American Medical Journal suggested that the use of shortcut keys significantly cuts down on repetitive stress, and reduces instances of carpal tunnel syndrome. Using shortcut keys reduces the use of the mouse and speeds up operations. For example, if you want to open a new document in Photoshop, you can click the File menu, and then click New, or you can abandon the mouse and press Ctrl+N (Win) or +N (Mac) to use shortcut keys. Keyboard Shortcuts, as their name implies, let you perform tasks in a shorter period of time.
That’s why the Photoshop application uses keyboard shortcuts. A wise man once wrote “time is money,” and Photoshop is a program that can consume a lot of time.
