em dash supremacy—my friend introduced me to this and i haven't looked back since.
alt+0151 on PC, ctrl+alt+minus for word if I remember right. On mobile you go to more symbols, hold down the minus, and slide to the longest one.
Both require numeric keypad though- but using a minus and a space after can work as a substitute--as well as 2 minus signs (plus Lemmy happens to convert that to an em dash) - but like THAT? treason. absolutely not.
You can even join more than 2 independent clauses together as shown above.
