Underscore

UnderscoreAlternatively referred to as a low line, low dash, and understrike, 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.

How do I create an underscore?

To create an underscore hold down the Shift key and press the " - " (hyphen) key next to the 0 on the top row of your keyboard.

Underscore and underline

An underscore is much different than an underline. If you are trying to underline any letter, number, or other text, the underline feature should be used.
