What Is a Backslash on a Keyboard?

The backslash key is the key that produces the "\" character. While it is rarely used in standard documents, it's commonly used in programming, web development and other technical areas.

Windows uses the backslash key to separate directories. Users who wants to access a "Music" directory stored in an "Audio" directory on the C drive can access it by typing the following command: cd C:\Audio\Music.

Linux and UNIX-based computers, on the other hand, use the forward slash character to access directories. Backslashes are often used to split one line of code into multiple lines, which helps make code easier to read.
