Issue description

Autocomplete hijacks home and end keys. This makes writing code very annoying as you need to speficically close the autocomplete popup before you can continue coding.

Autocomplete should use only strictly necessary keys it needs to work but not keys which are usually used when writing a line of code. Acceptable keys would be up/down arrow keys, page up/down, esc.

Steps to reproduce

1. First write this

var idget_parent()

2. Then add = between id and get_parent() to open the autocomplete popup.
3. Try to move to the end of the code line by pressing end key

-> It doesn't work. Autocomplete popup has got the focus and selection moves to the end of the list.
