The 'special' key's on a PC's keyboard have no ansi code. Also, since
you are using linux, there is not even a garantee that the keyboard
used is in fact a PC keyboard. I'm writing this on a VT220 clone.
Assuming you can be sure your program will only run on a PC console
you can either use nested case statements to filter out the proper
keys, or write your own keyboard input function using your own
keyboard code type.
