Disabling auto-completion of closing bracket

I've been using Intellij for a few years. Today I downloaded WebStorm to give it a go.

In JavaScript files, I'm getting an auto-completion that I would like to turn off but I cannot find the configuration option for it.

Here's the sequence of events.

- I'm typing in a JavaScript file.
- I type a dot after a variable name.
- A list of members to choose from is displayed in the auto-complete dialog.
- I press the Tab key to select a method.
- The method name is auto-completed along with the opening and closing bracket.

How can I get the auto-complete to do everything described except enter the closing bracket?

Cheers.
