Underscore

The underscore ( _ ) is a symbol found on the same computer keyboard key as the hyphen. The underscore is commonly used as an alternative to the space key when the space is not allowed. For example, in computer programming, a variable may be named $my_variable since spaces are not allowed in a variable name.
