The keyboard is a tenkeyless type that allows you to effectively use the space around your desk. ■ The silicone rubber attached to each keytop reduces the key-pressing sound by more than 90% compared to conventional products. It is suitable for use in places and times where noise is a concern, such as public facilities, conference rooms, late at night, or early in the morning. ■ The upper row of the keyboard is equipped with "hotkeys" that allow you to quickly execute specific functions. You can perform 9 types of operations, such as starting the media player, adjusting the volume, and brightness, by simply pressing the dedicated keys. ■ It is a wireless type that can be used immediately by simply inserting the receiver unit into the USB port of your computer. Since you can connect the keyboard and mouse with one receiver, it is also recommended for thin computers with few USB ports. ■ No special drivers are required, and you can use it immediately by simply connecting it.
