Anti-ghosting on a keyboard refers to the ability of the keyboard to register multiple simultaneous key presses without any of the keys being "ghosted" or ignored. This is particularly important for gaming and fast typing, as it ensures that all the keys you press are accurately registered by the computer. Keyboards with anti-ghosting technology typically have a higher number of key rollover, which means they can handle more simultaneous key presses without any interference. This feature is especially useful for gamers who need to execute complex key combinations quickly and accurately. **

To retrofit media keys on a PC keyboard, you can use software or hardware solutions.

Hardware solutions involve purchasing a separate keypad with media keys and connecting it to your PC. Another option is to purchase a keyboard that already has media keys built-in and replace your existing keyboard with it. **
