Tab instead of Enter / Return for autocomplete

I often find myself slightly annoyed by the autocomplete feature, even though I also really enjoy the feature.

When I know what I'm typing and typing fast, autocomplete sometimes inserts statements I don't want. For example, if I am working with a test wave named test: if I go to the command line, type test and hit return, instead of seeing the wave test printed I'm going to see the function MarkPerfTestTime inserted and then get an error that I'm using the function wrong.

Why not use TAB instead of RETURN for the autocomplete? This would solve the problem and be consistent with the default in Linux, Microsoft Powershell, etc.
