The Logitech 105 Gaming Keyboard features six programmable G-keys that make complex actions simple, and game mode switch, so you can easily disable the Windows key with one button so your game won't be interrupted. G105 also features LED backlighting that can be set at two different levels, or turned off all together, and multi-key input, which allows you to press up to 6 keys at once and have each register perfectly. This keyboard also features instant media access, with convenient one-touch controls that put instant access to volume control, mute, pause, play and forward all within easy reach, and easy-to-use set up software.
