Another mapping tip! Because going to Supercruise and Hyperspace Jump are used so much I mapped them (Options/Controls/Flight Miscellaneous) to the Spacebar and right shift buttons, simply because they were the 2 largest buttons on my keyboard. I still have J for FSD toggle as a secondary.
You'll often find you can comfortably map the same button 3 or 4 times without causing any conflicts as they are doing unconnected things. For example when you are going to supercruise with the spacebar you aren't selecting something in a menu.
