Q. Does Chicago have any recommendations for capitalizing digital copy that will appear as part of a GUI display? I am working on a project that includes a series of steps—and subsequent error feedback—for setting up a digital camera. I am wondering if I should follow CMOS 8.160 (“Principles of Title Case”) or if there is something else that applies to digital media. Thanks!
A. Title case is good for labels (e.g., for icons or section heads); sentence case is better for instructions or captions that are like sentences. If you can choose only one style, sentence case is safe for most purposes, whereas title case is going to look weird for any text of more than a couple of words. Click Here looks fine; Make Sure All the Calibrations Were Correctly Entered—not so much.
