Along with Davel23’s suggestion, figured it was worth mentioning that the backslash in my earlier comment’s markdown (visible using their suggestion to view the source) is acting as an escape character. This is pretty common for formatting codes and programming languages but not universal. If you’re looking to get a similar effect elsewhere and the backslash isn’t working, try using the phrase “escape character” and the language/application/website name in your preferred search engine to see if it’s documented somewhere.
