He might consider getting a Gameboard which will allow for easy access to often used key presses like the autopilot mode and others. I have a Logitech G-13 Gameboard which i've strategically placed alongside my chair and at hip height. I use it for snap and toggle views of the two MFCD's(really usefull), AP, radio communication, and HOTAS functions I need to map to keyboard including slew control, the gameboard comes with an 8 way hat.
