For anyone searching for a way to do macros in F1 2016, I think I may have stumbled upon a reasonable candidate. G-Hotkey (g-hotkey.com) is a free program that allows you to reassign keys or assign macros to keys (I have no connection to it, by the way) and it works with directx/directinput/etc. In just a few hours tonight I was able to figure out how it works and was able to program a couple of buttons to navigate the MFD. I had one button that would select each fuel mix. A button to set brake bias forward and another to set it to the rear. Two buttons each for diff and downforce. I don't know if this is the best solution or even a reasonable solution, but it's something others might find interesting to examine for themselves. My plan is to use the innards of a numeric keypad and add some buttons to my G27 wheel so I never have to take my hands off the wheel to easily operate the MFD.
