AlchyMyth, thank you! I knew it had to be something like that, but couldn’t find it. I didn’t search for it under “styling page link” – just under pagination, which gave me all sorts of info about creation of the pagination code, but not how to implement it!
Thank you, thank you!
For anyone else looking for this info, the answer is to add
<!–nextpage–>
where you want a page break in your post. Simple, if you have the info – impossible without it.
