Raemon’s advice (below) guided me to click upon a small, gray “\vdots” icon at upper right; this allowed me to edit the markup and complete the essay (however, no way to include newlines in BibTeX reference-entries ever was evident to me; also the text-sizing options were not orthogonal to the other formatting options, and hence worked inconsistently).

For which help, thank you Raemon! :)
Huh—you should be able to edit the post. Do you see the hover-menu in the top-right corner of the comment when you mouse over it?
