I get distracted by auto complete and they usually stay in front of the code, so I can't read it. I find it annoying when I'm pairing with someone that uses it and the auto complete/type hint/whatever pops up and covers most of the code I was trying to read

Working in a code base every day I end up creating a mental map of the code and the data, so it's not hard to find stuff I'm looking for. When that doesn't work, a global search or find/grep helps.
