In word processing, an embedded command is a sequence of special characters inserted into a document that affects the formatting of the document when it is printed. For example, when you change fonts in a word processor (by specifying bold type), the word processor inserts an embedded command that causes the printer to change fonts. Embedded commands can also control the display screen, causing it to display blinking characters or produce other special effects.
Embedded commands are usually invisible when you edit a file, but many word processors support a special mode that lets you see these commands.
