You can accept completion suggestions by pressing Tab instead of &shortcut:EditorEnter;. In this case the suggestion replaces the characters to the right of the caret.

Another way to accept suggestions is by pressing !. In this case the suggestion will be added prepended with negation, which may be useful for boolean expressions.

To select different keys to accept suggestions, open settings &shortcut:ShowSettings; and navigate to Editor | General | Code Completion | Insert selected suggestion by pressing space, dot, or other context-dependent keys.
