If you want to delete a paragraph, you simply remove it, without leaving a trace. It is equally easy to insert a word, sentence, or paragraph in the middle of a document. Word processors also make it easy to move sections of text from one place to another within a document, or between documents. Most standard word processing features are supported, including footnotes and mail-merge but no tables or columns. The interface uses customizable toolbars, and the editing screen is a zoom-able draft mode that optionally displays headers, footnotes, and footers.
