macOS Tip: Text Clippings
Text Clippings in macOS allow users to save text by dragging it to the Desktop or Finder, creating a standalone .textclipping file. This feature, present since at least Mac OS 9, facilitates easy reuse of text across apps like Pages, Mail, and Xcode. Users can quickly view or copy text snippets via Quick Look or double-clicking the clippings. Organizing clippings in dedicated folders can enhance efficiency and minimize desktop clutter, although compatibility with other platforms may be limited.
