Help me turn off this UI feature

It looks like some sort of tire contact patch icon - I have very few plugins installed, just enough for sim dash and Crew Chief to work. I can't figure out what UI element this is and how to disable - can anyone assist or tell me how I can determine?

 

It's default is Ctrl+Alt+M

 

Is there a list of ALL
keyboard - shortcuts?
For printing?
DC

 

Thanks all - will give that a try when I get back to the game. Just starting to mess with it a little more after owning it for quite a while (needed something with more AI racing after having a little one).

 

Does anyone know where such a keyboard commands list can be found?

 

Pretty much everything should be in Settings -> Assign.

 

Something like THIS maybe?

 

Thanks so much!

 

Changing:
"Display TGM":1,
to:
"Display TGM":0,
in player.json should prevent it from being on by default when the game starts.
