I was told by a Dell tech support person to press the FN key plus power switch to do something I might need to do. Upon my asking him where is the FN key, he said it would be between the Alt and Ctrl keys. On the left side of the keyboard that is were the "Window" emblem is to switch to the Start Menu and on the right is a key with a rectangle and three horizontal bars in the middle. Is this the FN key? Thanks for any help you can give.
