About Keyboard Shortcuts & System Commands
Keyboard shortcuts are keys or mixtures of keys that offer an alternative way to do something which you’d commonly do with a mouse.
once the shortcut has been created, you may assign a keystroke to that windows shortcut. click inside the Shortcut key field and press a letter. for example, if you press "p", the shortcut key will automatically be made to Ctrl + Alt + P. which means that if stored, pressing Ctrl and Alt and P will run that shortcut.
