Notepad is a simple yet powerful application that the author always has open. They use it to keep notes for work and home by saving files to their desktop and deleting them when finished. Notepad has useful tools like automatically inserting the current time and date, word wrap for easier reading and writing of notes, and find and replace for long documents. It can also clean hidden formatting when copying from Word and pasting into other programs, and allows printing of notes as an alternative to Word for basic text documents.
