Text Replacement is a feature found in many software applications that allows users to create shortcuts for frequently used phrases or text. By typing a specific abbreviation, the software automatically replaces it with the longer text, saving time and effort in typing. This function is commonly used in word processors, email clients, and mobile devices. For example, typing “addr” could be set to automatically expand to a full address. This helps streamline communication and enhances productivity by reducing repetitive typing tasks.
