Accept basic code completion with C-y

[elshize]

Hi all, I was wondering if anyone knows if it is at all possible to customize the shortcut for selecting code completion? Instead of pressing Tab or Enter to complete the selected entry, I'd like to use Ctrl-Y. I cannot find any way to do that, I can't find any mention of it online either. There doesn't even seem to be an action for this; the only one that I found was for ML completion, which is not what I want.

Any suggestions welcome, thanks!
