I believe I was previously told that there are some secret C symbols
wherein if you create a variable of a particular name, it acts as a hint to
the driver to trigger particular behavior.

I can't at the moment find the names of the symbols or what they do, but
I'll look around. Maybe you can find it before I do based on that knowledge.
