Currently I have caps lock remapped to escape for this. There's a few different options for doing that but on Sierra the only working one I found was the currently in development Karabiner Elements.

Hello,

Is there a keyboard shortcut for autocomplete other than escape?

Or is there a way to remap the autocomplete keyboard shortcut?

Thanks,
Josh
