What is a process of inserting replacing and deleting text in a business letter?

The process of inserting, replacing, and deleting text in a business letter typically involves using a Word processing software. To insert text, position the cursor where you want the new content and type; for replacing text, highlight the existing text and type the new content to overwrite it. To delete text, simply highlight the unwanted text and press the delete or backspace key. Always remember to review the letter for any formatting changes after making edits.
