Java – eclipse content assisted authentication key

I can't find any documentation about changing the shortcut for verifying content assisted selection

I mean, for my exact case, when content assist is turned on, I want to verify its proposal by pressing enter (its work), but it is never the same as any other key, such as [or (. Which key verification proposal do I want to choose

Even if I need to edit the configuration file manually, if someone has this answer, it will be perfect!

I checked org eclipse. jdt. ui. Prefs and org eclipse. wst. jsdt. ui. Prefs failed

thank you.

Solution

You look unlucky The eclipse Mars document discusses content assistance and explains:

Completion can be triggered by user request or can be automatically
 triggered when the "(" or "." character is typed:

public char[] getCompletionProposalAutoActivationCharacters() {
    return new char[] { '.','(' };
}

Since these characters appear to be hard coded, you need to implement your own content assistance Maybe it's enough to override the existing simple derivation in this way?
