Steps to reproduce the problem:
1. I want to type the word 'click' and <ENTER>
2. Autocomplete suggests 'clicked'
3. When I press <ENTER> after typing 'click' autocomplete adds 'ed' and makes it 'clicked'

What is the expected behavior?
I should be able to press <ENTER> without autocomplete filling in the suggested word.

Apply autocomplete only on <TAB>.

What went wrong?
To cancel autocomplete I have to press <ESC> and then <ENTER>. It is kind of annoying.

Did this work before? N/A
