• Word processors vary considerably, but all word processors support some basic features. Word processors that support only these basic features (and maybe a few others) are called text editors e.g. Word Pad, Note Pad etc. All word processors provide the following basic features:
• Insert text: Allows you to insert text anywhere in the document.
• Delete text: Allows you to erase characters, words, lines, or pages as easily as you can cross them out on paper,
• Cut and Paste: Allows you to remove (Cut) a section of text from one place in a document and insert (Paste) it somewhere else.
• Copy: Allows you to duplicate a section of text.
• Page size and margin: Allows you to define various page sizes and margins, and the word processor will automatically readjust the text so that it fits properly.
• Search and Replace: Allows you to direct the word processor to search for a particular word or phrase. You can also direct the word processor to replace one group of characters with another everywhere that the first group appears.
• Word Wrap: The word processor automatically moves to the next line when you have filled one line with text, and it will readjust text if you change the margins.
• Print: Allows you to send a document to a printer to get hardcopy.
• What is meant by paragraph formatting: Formatting applied on a paragraph is called paragraph formatting. Paragraph formatting includes line spacing, paragraph spacing, indents, alignment, tab stop, borders and shadings etc. Most of the paragraph formatting is done using paragraph dialog box, horizontal and vertical Ruler elements.
