It wasn't obvious, at least to me, that "Use smart paragraph selection" means "Don't automatically include the CR/LF character when selecting the last word on a line." In case anyone from Microsoft reads this who is in a position to change things, I'd like to suggest that it would be helpful if clicking or hovering the mouse over an option would bring up a "tip" explaining the option in more detail.
