Keyboard table for in-flight controls. This table contains the internal key codes for the flight keys (see page 142 of the "Advanced User Guide for the BBC Micro" by Bray, Dickens and Holmes for a list of internal key numbers). The pitch, roll, speed and laser keys (i.e. the seven primary flight control keys) have bit 7 set, so they have 128 added to their internal values. This doesn't appear to be used anywhere.
