A keyboard cover is a thin, flexible layer made of silicone or plastic that fits over the keys of a computer keyboard. Its primary purpose is to protect the keyboard from dust, spills, and wear, helping to extend the life of the device. Keyboard covers are available for various types of keyboards, including those for laptops, desktops, and tablets. In addition to protection, keyboard covers can also enhance typing comfort and provide a personalized look. Many covers come in different colors and designs, allowing users to express their style. Some keyboard covers even feature printed shortcuts for software like Microsoft Word or Adobe Photoshop, making them useful for specific tasks.
