Ah, great! That makes sense. Many thanks!
I'd got used to automatically lifting off a key very briefly to drift etc.
I'm not sure after playing TM for 14 years that I can get used to a different key arrangement! However, I'll have a play, and perhaps look at getting a better keyboard, this is getting a little tired anyway. It's funny how you adapt to things without thinking whether it could be better.
Everyone must have their own way of pressing the keys, mine is with the middle finger of my left hand on the up arrow, and the index, middle and ring fingers of my right hand on the left, down and right arrows. I.e. left hand for go, right hand for control. Perhaps changing the up arrow to the right shift key would be the closest match.
After a quick check ...
Yup, adding right shift to the accelerate group works fine, and now I can do left spin turns as well as right!
Thanks again!
