How to disable inline code completion in IDEa

It is very very simple to write your code using TAB key.

And if you don’t want to lose your skills and become a passive vegetable, there are several options to disable this jIDEa feature:

1. Disable Full Line Code Completion plugin - this is the most radical approach
2. goto Settings -> Editor -> General -> Inline Completion -> tune it as you wish
3. Check Jetbrains Docs
4. Or keep going on your degradation path
