I'm using Eclipse 20190917-1200 with PyDev for Eclipse 7.4.0.201910251334. Whenever I move my cursor into a key word it's highlighted as shown below. I can't find this color anywhere in the PyDev settings. One question is, what is that behavior called, but more importantly, how can I change that insane color!
Go to general > editors > text editors > annotations > Occurrences (PyDev)
and change the colour or uncheck it.
Hope this works for you !!
