xD, it’s done by typing three times “-” or “*” next to each other with nothing else on the line itself and the lines before and after. So to illustrate it with quotation marks:
“(Empty)”
“—” (or “***”)
“(Empty)”
Note that in the above example, i had to leave another empty line in between the lines. So it’s not exactly correct. Unfortunately, without a break line, I can’t even illustrate it. So, this is done from necessity. Though, it means that technically, the stars below were one “/” removed from becoming a line.
