As the previous poster said, there are some types of keyboards that limit your keypresses. I remember that USB keyboards or newer keyboards in particular were often limited due to the nature of how USB is, how limiting it is or how limiting the software is that handles it. This may be better with newer motherboards and USB versions, but I'm not certain.Quote:

- 6-key rollover: Most standard keyboards, including many laptop keyboards, have a 6-key rollover, meaning they can only reliably detect up to six simultaneous key presses.
- Mechanical keyboards: Many mechanical keyboards, especially those designed for gaming, have "anti-ghosting" or "n-key rollover" which allows them to accurately register many more simultaneous key presses, sometimes even all keys at once.
The one I got has 19 anti-ghosting keys and the anti-ghosting technology prevents USB from being such an issue. It's a pretend mechanical keyboard because a lot of us miss the old real mechanical keyboards.
- Membrane keyboards: These keyboards, common in laptops and many desktop models, often have lower rollover capabilities.
- Mechanical keyboards: Mechanical keyboards with better switches can support higher rollover due to individual switches isolating key presses.
