Backslash

Also called reverse solidus or backward slash.

How to type it

Right pinky.

Common uses

• Windows file paths separate folders with backslashes, as in C:\Users\Ada.
• Web addresses use forward slashes, so a backslash in a URL is usually a mistake.

Less common uses

• In code, a backslash is an escape character: \n in a string means a new line.
• ASCII added the backslash in the 1960s so that programming languages could write the logical operators /\ and \/.
