These backlights can also be set to pulse, sort of like the old Dell XPS laptops, and are available in a few different speed settings.
The keyboard also includes a convenient "gaming mode," which disables the Windows key (granted, many modern games have started ignoring this key). Genius' Imperator Pro also has a sizable on-board cache that will prevent command overflow.
Also included in this package are six "media keys," effectively made to control multimedia programs like Windows Media Player without tabbing to the program.
As a whole, it's very similar to the old Logitech G11, albeit a bit newer and with cooler lighting schematics.
