A keyboard cover usually refers to something that covers a computer keyboard, but may also refer to something that covers a musical instrument keyboard. This article focuses primarily on computer keyboard covers. There are many different types of computer keyboard covers, but they can generally be grouped into the following categories: keyboard bags, keyboard protective covers, keyboard protective skins, and keyboard stickers.
A computer keyboard bag is a simple sack that is pulled over the keyboard when it is not in use. This type of keyboard cover's primary purpose is to keep dust from entering the keyboard. It is usually waterproof so as to resist rain and spills. Keyboard covers of this type have become less common as keyboard prices have gone down, newer keyboard designs have made dust less of a problem, and other styles of keyboard covers have become less obtrusive.
Another type of computer keyboard cover is the keyboard protective cover. Keyboard protective covers are made to resist wear and damage when the keyboard is in use. These covers are usually clear, and are molded so that they fit perfectly over a keyboard’s keys. These features allow the keyboard to be used while the keyboard cover is in place, protecting the keyboard at all times.
Keyboard protective skins are another common type of keyboard cover. Keyboard protective skins are long, transparent sheets that adhere to a keyboard. They protect the keyboard from dust and direct spills, but may not work on every part of the keyboard as they do not usually cover the entire device. Protective skins are often hard to use initially, as they make keys harder to press. Over time and use, the skin bends and molds itself to the keys, becoming easier to use.
Keyboard stickers are a type of computer keyboard cover that changes the aesthetics of a keyboard. They adhere to the surface of a keyboard, and are usually difficult to remove. Common reasons for using keyboard stickers include changing the color of a keyboard, making the letters bigger, and adding information on where new input functions can be found. Keyboard stickers generally do not protect keyboards, but can be used to restore old keyboards that have had their numbers and letters worn off.
Musical instrument keyboard covers come in styles similar to those of computer keyboard covers. Musical instrument keyboards, however, are also commonly stored in travel cases. These cases are both sturdy and padded, and protect the musical instrument from damage during transport.
