If you've ever written for a newspaper or magazine, you might be familiar with "TK" — a journalism shorthand for "to come" that marks placeholder text you need to fill in later. It's a handy way to keep writing when you don't have a fact, link, or quote ready yet.
Now Buttondown has your back: when you type TK (or TKTK, Tk, tk — we're not picky) in your email, you'll see it highlighted right in the editor. And when you go to send, you'll get a friendly warning reminding you to fill in those placeholders.
No more accidentally sending "The event starts at TK" to your subscribers!
(p.s. — credit where it's due. We stole this idea from Ghost. Thanks, Ghost!)
