How to adjust Script template

Hi.

I’m trying to use the Stage Play (US) template to write an opera libretto, and I think I can make it work much better with one small adjustment. Currently, hitting ENTER reverts to character and TAB reverts to stage direction. I’m hoping there’s a way to have ENTER just be a line break, as lyrics require a lot of line breaks, and maybe SHIFT-ENTER or CONTROL-ENTER or something like that be character. This would save me an immense amount of frustration. Is there a way to do this?
