Hi,
I dont know why, but my editor not highlighting similar variable/function.
I tried to look about option in the preferences, but I didnt found it.
Example:
Hmm ... working OK here with uVision v5.32.0.0:
What version do you have?
I had v5.31.0.0.
I updated the version to v5.33.0.0 but still the editor doesnt highlight.
