Code-completion only by "Enter" key

That's all. And... read from bottom to top, because it forum's bug.
In this I'll write why I'm asks about this option. phpStorm developers against code-tip functional (that really weird, but everybody has his own crazy ideas - we all are just humans). So, i found plugin "Extended Code Sense" and this plugin works great, except one very annoying thing: code puts from pop-up window by pressing any key, and it brings errors in code.
Question is: How to configure Code-completion to trigger "select" only by "Enter" key? Now it's triggered by pressing any key, and it's really bad. Think, it's not so hard to add this option :) Or, maybe, it's already exists. In some dark corner.
when i pressing "enter" in this forum's post editor, he puts caret over current string, not under. Well, maybe it's kind of joke from developers.
