Problem: When using kdb via keyboard it does not react to control
characters which are supported in serial mode.
Example: Chords such as ctrl+a/e/d/p do not work in keyboard mode
Solution: Before disregarding non-printable key characters, check if they
are one of the supported control characters, I have took the control
characters from the switch case upwards in this function that translates
scan codes of arrow keys/backspace/home/.. to the control characters.
