Nice, so it was worth asking! I'd completely overlooked clockwise/anti-clockwise rotation! Thanks :)
Would you still want a down button as well as drop? I like using down instead of drop because I tend to suddenly change my mind at the last moment but I can see that many versions of the game only have a drop button. I will implement re-definable keys when I figure it out.. I've found reading the keyboard without the bios hard to understand and I can only just see how I'd go about making the keys re-definable.
