Word wrap also occurs if you change the margins. In this case, the word processor readjusts all the text so that it fits within the new margins.

Note that word wrap inserts a soft return at the end of each line, not a hard return. Soft returns are invisible codes that the word processor utilizes. Hard returns are real characters inserted into the document.

Some word processors allow you to turn off the word-wrap feature. This is useful for writing programs and other types of formatted text where you want complete control over new lines.
