Known Issues and Hiccups

While we work hard to make Keyboardy smooth and reliable, there are a few known issues that may affect how it behaves on certain setups. Some of these are caused by keyboard hardware limitations, device capabilities, or differences in how various operating system versions handle keyboard events. This page lists those issues in plain language and offers tips or workarounds where possible. If something feels off or unexpected, you might find the explanation (and solution) here! And if not—please feel free to contact us, we’re here to help. 💙


N-Key Rollover

If you notice that certain key combinations especially when holding the Reflector key don’t register properly, your keyboard might be running into a hardware limitation called “N-Key Rollover.”

❓ What is N-Key Rollover?

Most regular keyboards can only detect a limited number of keys pressed at the same time. This is known as N-Key Rollover (or “key rollover” for short). When too many keys are pressed together—especially in certain combinations—some key presses may not be detected at all.

🛠️ How This Affects Keyboardy

Keyboardy relies on the Reflector key being held while you press other keys. If your keyboard can’t handle that specific combination (like Reflector + Another Key), it might not send both signals to the computer—which makes it seem like the key isn’t working.
In some cases, if you press a key while holding others, one of the keys you were already pressing may suddenly stop registering (as if it was released). This can cause letters to “not type” or behave unpredictably.
This isn’t a bug in Keyboardy—it’s a hardware limitation of many standard keyboards, especially laptop or low-cost models. It’s commonly known as a key rollover limit.

✅ What You Can Do

  • To detect if this problem does actually exsit, please visit this Microsoft project and check if the combination that you are pressing are being registered or not
  • Try a different key as the Reflector. Some key combinations work better than others on certain keyboards.
  • If you’re using a built-in laptop keyboard, try testing with a separate external keyboard.
  • Mechanical or gaming keyboards often support “Full N-Key Rollover,” which avoids this issue entirely.

Conflicts with Other Keyboard Software

If you’re using other programs that also listen for or modify keyboard input—like automation tools, text expanders, or accessibility software—you might experience unpredictable behavior in Keyboardy (like key presses not working as expected).

❓ Why This Happens?

These types of programs often “listen” to your keyboard in the background, just like Keyboardy does. If another program starts before Keyboardy, it may take priority in how your system handles keyboard events, which can interfere with how Keyboardy works.

✅ What You Can Do

  • Make sure to start all other keyboard-related programs first, then launch Keyboardy last. This puts Keyboardy at the top of the operating system’s keyboard event handling queue, giving it the top priority to handle key signals.
  • If a conflict still occurs, try temporarily closing other tools to see if the issue improves.
  • Let us know, we will identify the issue and try to fix it :).
