Documentation for code completion and hover settings

1. Is there a setting to disable automatic completion when I press enter? I would like enter to open a new line rather than select an completion.
2. What are the allowed values for hover key? I tried to set tab as the hover key but it does not work.

1. No unfortunately not in the current version, but this is on the wish list (Display completer if no matches, but do not activate any of the options #350). For the technical reasoning on why we cannot do this just yet see Continuous hinting should not trigger completer if there are no matches #334, Implement a workaround for #334 #335. However, if you can provide a reproducible example demonstrating where it is still a nuisance (still as I already added a workaround to suppress auto-invocation in a typical example demonstrated in Continuous hinting should not trigger completer if there are no matches #334) I will look into this.
2. Good catch! You can find the allowed values here:

It indeed would be better if we could include the enum values in the description field value. Would you like to contribute a fix by editing this file and creating a pull request?

You could also add information on some caveats for the Mac users, as I noted for my previous extension here (and maybe the link to the MDN page which describes to which physical keys they are actually mapped, also in the readme of the previous extension).

Thank you @krassowski, I have made a PR.

I tested the enter on a simple case of

x=1
x

and autocompletion refused to open a new line. But this scenario would never happen practically. So I am closing this.
