What is a Backtick?
A backtick is the little character that looks like a slanted single quotation mark that normally calls the key above the tab key home on a normal English keyboard. Otherwise known as the Marigold key, grave accent or backquote, the character is a tricky one simply because no one knows what to call it. However, in the land of computer programming, it is commonly referred to as the backtick character, so that’s what we’ll call it. Cool? Okay!
