This keyboard function is designed to perform specific tasks.
I own a Marvo KG760 Keyboard and I'm trying to understand its function. The manual says: "Pentru selectarea ratei de transmisie (normal sau rapid) apasati tastele FN + Q", which means "For choosing [transmission/input] rate (normal or fast), press the keys FN+Q". The label on the Q key reads: "Q / 80%".
Not really able to perceive the effect directly through your videos.
My idea is that using FN combined with Q lets you adjust the repeat rate when the Q key is pressed.
What other percentage choices exist?
Are there manual guides for performing FN + "key" across all keys or just specific gaming movement keys?
Open WIN + I > Ease of Access > Keyboard > Filter keys.
Enable Filter keys.
Adjust a setting (note the change and the original value if needed).
Then return to FN + Q options, check the percentage, and modify it.
Check if altering the setting also affects your "Filter key" preferences and vice versa.
The keyboard lacks a driver so I can't adjust the % settings. There are specific functions in the manual: FN+W, FN+Win, FN+[+-]... "FN + Q" lets you configure the repeat rate. I believe this function helps if you press a key continuously and want faster repetition without manually spamming. It might be useful for games where pressing keys automatically is preferred over manual input.
Try this:
In the Open field/box type "main.cpl @1 " (without quotes)
A keyboard properties window should appear.
I wonder if your keyboard FN options will show up or shift the rate indicators
Either actively (the rate indicators move when you press FN) or passively (you observe the current rate settings, close the window, go to your keyboards FN feature, adjust what you can, then reopen the window to check if the rate changed)
The goal is to find a method to clearly demonstrate or explain what FN + Q actually does and how you can use that result later.
I'm not certain how much detail you want to explore.
But I searched online about thinking and finding methods to measure key repeat rates while holding a key down.
I found this website: http://stereopsis.com/keyrepeat/
If you're generally interested in such topics, I considered using PowerShell to control the keyboard's repeat rate.
It seems like this:
The cmdlet to retrieve the rate is Get-itemproperty.
For example, with the path:
HKCU:\Control Panel\Keyboard\" -name KeyboardSpeed
My keyboard output shows:
KeyboardSpeed : 20
You can open PowerShell, run Get, and then use Fn+Q to monitor changes by re-running Get.
Just remember, don't let the registry data lead you into risky modifications. It probably won't work well...
I've used the site and the key repeat rate is consistently at 33ms, however activating the FN+Q function causes it to drop to 16-20ms.
In powershell it remains unchanged:
KeyboardSpeed : 31
PSPath : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\Control Panel\Keyboard
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\Control Panel
PSChildName : Keyboard
PSDrive : HKCU
PSProvider : Microsoft.PowerShell.Core\Registry
If followed properly, the function accelerates the speed of key presses. Under normal conditions it's 33, while fast mode ranges from 16 to 20. With FN+Q, your character should move quicker during repeated directional key presses compared to simply holding a key. You should notice the improvement directly.
I don't understand how this can assist you in the game. For instance, in CSGO, when you turn on it and press a key, such as W to move forward, it seems to stutter and behaves like you're continuously pressing and releasing the key even though you never let go.
The differences observed in the video are probably caused by external factors like internet speed, network performance, and computer settings.
Each key press could signify a single action, such as moving forward one step.
To advance quickly, pressing keys rapidly is necessary—each press counts as one step.
Repeating a key while holding it changes the behavior of the keyboard drivers, making multiple steps appear at the speed of the hold time.
Using a keypress-hold generally leads to faster movement compared to repeated key presses for each individual step.
This effect becomes more noticeable when hands or fingers become fatigued during extended play.
It’s possible that certain combinations, like FN+Q, achieve similar results, but speed is limited by how fast the system can process key inputs.
Your device might struggle with such high speeds, causing stutters.
The keyboard could be operating at varying repeat rates (20, 40, 60, 80, 100), and other elements like drivers or game settings play a role.
With a potentially unreliable keyboard, outdated drivers, and no clear instructions, it’s unlikely much can be improved.
This situation might attract more discussion in the PC gaming community.
