I Can Push How Many Keys at Once?
Keyboards usually suffer from something called ghosting. This occurs on many keyboards when pressing three or more keys and, due to the layout of the circuits in the keyboard, the keyboard thinks a key that isn’t being pressed is being pressed. The opposite problem, where key presses aren’t registered, is called masking or blocking, though the term ghosting is also used to cover both problems.
Gaming keyboards; because gamers will often be turning, strafing, advancing, jumping, shooting, holding down a voice button, and opening a map; can usually handle a half-dozen or more simultaneous keypresses
Someone at SteelSeries decided not to push the envelope when they could launch the mail truck. They claim that this keyboard takes special advantage of the PS/2 buffer to support the simultaneous pressing of every key on it at once.
I had to try this out. By pressing both palms against the keyboard, a macro capture tool registered 26 simultaneous key presses. Using one forearm and one hand, I got to 42. It appears that, with enough fingers, you could indeed push down every single key on the 7G, and it would report it all to your computer faithfully.
If you need more simultaneous key presses than your current gaming keyboard offers, this one isn’t about to run out. Like the above feature though, this has a lot to do with knowing you have the best, even if you can’t tell the difference, or the practical advantage for someone with only ten fingers is limited.
