DukeNukemForever: Maybe there is a mapping problem as on notebooks there are some keys missing. Also macbooks there work some functions only by shortcuts (page up, page down, etc), so also give a combination of command-key + arrow-keys and Alt-key + arrow-keys a try. If gog uses boxer as dosbox-gui there is also an option to simulate the numpad by pressing command+u. New numpad-keys are then 7,8,9-u,i,o-j,k,l.
Is there as bonus a reference card as extra to show all the shortcuts? What are exactly the keys for movement there So far I found only the reference card for amiga and there the shortcurts are as followed for the numpad:
7 Turn Left - 8 Move Forward - 9 Turn Right
4 Slide Left - 5 Move Backward - 6 Slide Right
-2 Move Backward -
I also found a thread on vogons about problems with Eye of Beholder 2. Solution there was to rebind the keys like in shooter games to the wasd-keys.
Thanks for advice. I have now found that if you press CMD and U when in game, it gives you keys 7,8,9 for turning and I, O,P for left,right and back. This works for all older GOG games in Beholder and Lands of Lore series
