You can make as many profiles as you like and switch between three of them on the fly by using the keyboard's M1, M2 and M3 buttons. You can use it to program macros, change the backlighting color and set up individualized profiles.
The Raptor K40 runs on Corsair's gaming software, which is thoroughly middle-of-the-road as these things go. That's impressive, considering my familiarity with the Dell and my relative lack thereof with the Raptor K40. Using the Ten Thumbs Typing Test, I scored 91 words per minute with a 0 percent error rate on the Raptor K40, versus 91 words per minute with a 2 percent error rate on a standard Dell keyboard. To be fair, while the Raptor K40 may not do much to improve your gaming skills, it's a typist's friend. The keys feel responsive, springy, pleasant - and almost exactly the same as just about every other rubber-dome keyboard I've ever used. In spite of the peripheral's smart design, however, it suffers from the same potentially fatal flaw as most other membrane gaming keyboards: the feel is not significantly different from the run-of-the-mill $20 keyboard I'm typing on right now. The keys feel smooth and easy to press, and I liked how the W, A, S, D and arrow keys are silver instead of black to help highlight them.
