Open and Edit Text Files on Your MacBook
As a MacBook user, you’ll be amazed how much information still flows across the Internet in plain, simple text. Text files would seem to be another anachronism in this age of formatted web pages, rich-text format (RTF) documents, and word processors galore. However, virtually every computer ever built can read and write in standard text, so text files are often used for
Information files on the Internet, such as FAQs (Frequently Asked Questions files)
README and update information by software developers
Swapping data between programs, such as comma- and tab-delimited database files
Here’s the quick skinny on opening, editing, and saving an existing text file:
Navigate to your Applications folder and launch TextEdit.
Press Command+O to display the Open dialog.
Click the insertion cursor anywhere in the file and begin typing. Or, to edit existing text, drag the insertion cursor across the characters to highlight them and type the replacement text.
TextEdit automatically replaces the existing characters with those that you type. To simply delete text, highlight the characters and press Delete.
After you finish editing the document, you can overwrite the original by pressing Command+S (which is the same as choosing File→Save), or you can save a new version by choosing File→Save As and typing a new, unique filename.
To exit TextEdit, press Command+Q.
