My keyboard layout changed by itself. The functionality of Ctrl and the Fn keys swapped, the functionality of Delete and Pause keys swapped and my arrow keys have an added functionality of controlling the brightness and volume of the system.

Since I'm using a laptop, the features of the function keys have also been interchanged, for example the volume control now switches the projector control. I also tried testing the keyboard on a different OS, but got the same results.

I'm using a HCL laptop and the keyboard behavior is of a Dell Vostro — I have no idea how this happened.
