In word processing, track changes is an editing command that is commonly used when you create an original document and make changes and want to keep track of the changes that are made to that original document. It is also a useful tool for collaborating on a document, as it allows multiple users to make revisions without losing the context of the original document.
Changes to text and formatting are noted in a number of different ways, depending on the word processing software you use. For example, Microsoft Office Word 2007 uses balloons to display deletions, comments, formatting changes, and content that has moved. You can also choose how tracked changes and comments are displayed, for example in a different font color.
In some word processing programs, track changes may also be referred to as edit mode.
