I was reading the git answers when I read this:

https://github.com/Ebazhanov/in-quiz-questions/blob/master/git/git-quiz.md#q56-which-key-press-return-a-set-of-suggestions-to-pick-from--when-writing-a-git-command

It states that auto-complete can be achieved with shift. In what context would this be? Isn't the universal auto-complete tab?

The mark note for algiorithms often looks like this:

apply(note1);
apply(note2);
apply(note3);
...

It would be more convenient to write

apply(note1, note2, note3, ...)
