The next time you need to close a few applications quickly, try Alt-F4. Use your left thumb to hold down the left Alt button while your left index finger presses the F4 button. The slow ineffecient way of doing this involves finding the mouse… clicking the File menu… clicking Close, Exit or Quit (whichever one you find).
Alt-F4 works for almost all applications. If there are no applications running, you can also use it to close the operating system.
