The underscore _ is the character with ASCII value 95. On the standard US 101/102 computer keyboard it shares a key with the hyphen on the top row, to the right of the 0 key.

It is used as a diacritic mark in some African and Native American languages. The underscore is sometimes used as an underdot (Unicode: COMBINING DOT BELOW) in romanized Arabic and Hebrew.

It is also often used instead of a space in computer operating systems, file names, and in World Wide Web URLs.

Some computer applications will automatically underline text surrounded by underscores: _underlined_ will render underlined. It is also conventionally used in this fashion on Usenet ? an ASCII-only medium ? to indicate underlining.

However, Microsoft Word changes text input between underscores to italics.

It is not a dash, and should not be used as such (although an apparent convention for text news wires is to use an underscore when a em-dash or en-dash is desired, or when other non-standard characters such as bullets would be appropriate). A series of underscores (like _________) may be used to create a blank to be filled in on a form. It is also sometimes used to create a horizontal line, if no other method is available.
