"direction" is coloured in brown in Arduino soft even if is not a reference w.

Is that normal or it is an error?

It is probably a keyword in a library and has no significance The keyword colours look nice but are not always useful

Oh wouldn't it be nice if they dropped the GNU compiler and switched to using clang with an updated IDE for true keyword and source code symbol navigation of simply double-clicking to to find declaration, definitions, etc.

And while we're (OK while I'm) dreaming use 'uncrustify' for a much better and user configurable code reformatter.

Maybe once the avr-llvm module is done being developed.
