Easier suggestions in Intellij IDEA (no `CTRL+Space` and fuzzy search)

Question

I've installed IDEA today, on macOS and am wondering a couple of things to adapt usability to my needs:

• how to always show autocompletion automatically, as a sort of continuous suggestion , rather than having to always manually press ⌃Space ?
• how to make the search among autocompletion fuzzier , without needing to type all the initial letters? Something like typing "fb" and it will match the variable foobar , rather than having to type "foob".

Answer 1

• Yes, this is achievable. Go to Settings -> Editor -> General -> Code Completion and check 'Show suggestions as you type'
• Partially achievable. You have to go again to Settings -> Editor -> General -> Code Completion and uncheck 'Match case'. This will help you with the completion but the results are not always as expected.
