Shortcut keys help provide an easier and quicker method of navigating and executing commands in the computer software. Shortcut keys are performed using the Alt key ,  Ctrl key, or Shift key in conjunction with another key. The de facto standard for listing a shortcut is listing the modifier key, a plus symbol, and another key. In other words, "Ctrl+S" is telling you to press and hold the Ctrl, and then press the S at the same time.
