That probably explains everything from a statistical perspective about this em dash topic. I didn’t know that — Thanks.

Or Microsoft word. Many common tools in different contexts make it easy to do.

As it turns out, the differentiator is the level of literacy.

And whether the user cares to ‘write properly’ to boot. I love using dashes to break up sentences - but I rarely take the time to use the proper dashes, unless I’m writing professionally. I treat capitalization the same way - I rarely capitalize the first letter of a paragraph. I treat ‘rules’ like that as typographic aesthetic design conventions - optional depending on context.

You can also hold down the hyphen key and select it from the popup menu. En dash lives there, too.
