Text Expansion is a productivity technique that allows users to create shortcuts for frequently used phrases, sentences, or even paragraphs. By typing a short abbreviation, users can automatically expand it into a longer text, saving time and effort in writing. This is especially useful for repetitive tasks like responding to emails or filling out forms. Many software tools and applications support Text Expansion, enabling users to customize their shortcuts. Popular examples include TextExpander and PhraseExpress. These tools can enhance efficiency, reduce typing errors, and streamline communication in both personal and professional settings.
