I guess it's important to note that I would use the right shift for this. I have the ability to choose on-the-fly rather than be forced into one or the other by a typing method that I learned in school. I could still do it with the left shift but it's not the one I would choose for this.

It's probably fairly obvious what I think about the taught-at-school touch typing method. It's a decent middle-of-the-road option that's intended to be easy to teach and to work for most people in most situations; that's all.
