I never use an en-dash I just use an em-dash and lower the font size.
How do you do that?
I click on the icon and I see the option to use it.
If that is not the proper way to punctuate, then you should not use it. Proper punctuation is important when trying to get your message across!
I can't be bothered to follow all the rules of punctuation.
If you use incorrect punctuation people are going to think less of you, I'm afraid. It doesn't sound like the way you are doing things is all that convenient anyway. Why not just learn the correct use of this punctuation?
