Keith,

The F key issue may be as simple as a shift key. Laptop F keys sometimes have THREE “pages”: Normal, Shift, and Function, the last being toggled by an Fn or Fcn key. It may be gray or subdued compared to the regular keys; may or may not have an indicator similar to Caps Lock or Num Lock; and probably latches (remains in the state of the last key press, unlike the Shift key). In other words, you may have toggled it without being aware of it.

The Fn Shift on my HP laptop is at lower left, between the CTRL and Windows keys, but I have also seen them in line with the F keys themselves.

HTH,

Richard
