I have been using the em dash in writing forever - in Word, for example, you type a word, then space-hyphen-space, then you type another word and the hyphen is autocorrected to an em dash.

I don’t regularly use en-dashes, cause I don’t know how to make them.

If you're on windows and have a numeric keypad, it's alt-0150.

I’m pretty sure Word’s autocorrect for space dash space is endash not emdash, no?

it’s usually space dash dash space across most word processors.

I picked up the habit a couple years ago of just undoing the autocorrect to an em dash and leaving it as two dashes to avoid accusations -- now it’s stuck with me

Word’s autocorrect inserts en-dashes.
