TextEdit can automatically turn the Internet addresses in your document into links. This feature is called “smart links.”
For example, with smart links turned on, if you type “www.apple.com,” TextEdit turns it into a link that opens that website. And if you type “mailto:annejohnson1@mac.com,” TextEdit turns it into a link that creates an email message for Anne Johnson.
To apply smart links as you type:
Choose Edit > Substitutions, and then select Smart Links from the submenu.
To automatically use smart links in all new documents, choose TextEdit > Preferences, click New Document, and select “Smart links” below Options.
To apply smart links to text you’ve already typed:
To use smart links for only part of a document, select that part, choose Edit > Substitutions > Show Substitutions, select Smart Links, and then click “Replace in Selection.”
To apply smart links throughout the document, choose Edit > Substitutions > Show Substitutions, select Smart Links, and then click Replace All.
Smart links are automatically applied to any additional text you type in the document.
To stop using smart links:
Choose Edit > Substitutions, and then choose Smart Links from the submenu to deselect it.
