Authors who create and publish several articles often use TK as a placeholder for content which is considered still “To Come.” This is often considered the editorial equivalent of using //TODO , so that you can come back to continue editing and crafting your content.

When placing TK (or tk ) within a post or page in Ghost, Ghost will highlight any usage of TK within the margins of the editor, as well as provide a warning, if it looks like you're about to publish a post that's missing additional content.
