Problem / Steps to reproduce

Hi, thanks for your great work. I've searched all around the web but I didn't find anything that fits. I would like to know if there is an alternative way to trigger autocompletion that is not **tab. I want (supposing) to bind it to ^E for example. Thanks again and bye.
