Jet 75 Magnetic Keyboard Advanced Features Explained

This article explains the advanced features available for the MCHOSE Jet 75 magnetic switch keyboard, including actuation settings, Rapid Trigger, dead zone adjustment, key remapping, macro recording, advanced key functions, performance settings, firmware updates, and factory reset options.

Trigger Settings

Trigger settings allow you to control how far each key must travel before an input is registered. In M HUB, you can configure actuation distance, Rapid Trigger sensitivity, and dead zone parameters for all keys or selected keys.

How to Configure Trigger Settings

1. Select a configuration.
   Only custom configurations can be edited. Official preset configurations, including Beginner, FPS, and Extreme, use predefined parameters and cannot be modified directly.
2. Create or select a custom configuration.
   To personalize the trigger parameters, create a new custom configuration or select an existing custom configuration.
3. Select the keys you want to adjust.
   You can apply the same parameters to the entire keyboard or select individual keys for separate adjustment.
4. Modify the parameters.
   Adjust the actuation distance, Rapid Trigger sensitivity, and dead zone settings according to your preferences.

Hover your pointer over a parameter or information icon in M HUB to view additional explanations for the available settings.

Default Trigger Parameter Reference

Key Remapping

Key remapping allows you to replace the default function of a key with another keyboard function, shortcut, macro, or supported advanced function.

How to Remap a Key

1. Open the Key Remapping page in M HUB.
2. Select the key function you want to assign.
3. Drag the function onto the target key in the keyboard layout.
4. Confirm that the new function appears on the selected key.

To restore all key assignments to their original functions, click Restore All Defaults.

Default Key Layer: Windows Mode

The default key layer contains the standard keyboard functions used in Windows mode. Pressing a key triggers its default function without requiring any additional key combination.

For example, if you drag Q onto Z, pressing Z will trigger the function of Q. The original Z function will be replaced.

Fn1 Layer: Windows Shortcut Layer

The Fn1 layer is used for shortcut functions in Windows mode. Press and hold Fn together with another key to trigger lighting controls, multimedia controls, or special shortcuts.

For example, pressing Fn + N or Fn + M can be used for volume adjustment if configured.

Mac Layer: macOS Mode

When the keyboard is switched to macOS mode, the key bindings are displayed based on the Mac layer. This layer contains the basic key functions for macOS.

Fn3 Layer: macOS Shortcut Layer

The Fn3 layer is used for shortcut functions in macOS mode. You need to remap a key to Fn3 first. Then press and hold Fn3 together with another key to trigger the assigned function.

Example: In the default key layer, drag Fn2/Fn3 to the W key. Pressing W will now activate the Fn2/Fn3 layer instead of the original W function. In the Fn2/Fn3 layer, drag Z to the Q key. Pressing W + Q will now trigger Z.

Macro Recording

M HUB provides 16 preset macro recording slots on the right side of the key remapping settings page.

How to Record and Assign a Macro

1. Go to the key remapping settings page.
2. Click the edit button next to a macro slot.
3. Enter the macro recording interface.
4. Edit the macro command name if needed.
5. Adjust the loop type if needed.
6. Record the macro command.
7. Save the macro.
8. Drag the saved macro command to the key you want to assign it to.

Once assigned, pressing the selected key will trigger the macro.

Advanced Key Functions

RS Advanced Key Function

RS activates the key that is pressed deeper when two selected keys are bound together.

For example, if A and D are bound together and A is pressed deeper than D, then A will be activated while D will not. If both keys are fully pressed, both keys can be activated.

SOCD Advanced Key Function

SOCD allows two selected keys to be bound together. Depending on the selected trigger rule, one key can be prioritized, or both keys can cancel each other out when pressed at the same time.

Dynamic Key Stroke / DKS

DKS allows a single key to trigger up to four different functions based on how deeply the key is pressed.

By setting different actuation ranges, you can decide which function is triggered at different key travel depths.

MT Advanced Key Function

MT allows one key to trigger two different functions based on how the key is pressed or tapped.

TGL Function

TGL allows continuous triggering after a key is pressed once. Press the key again to stop continuous triggering. This removes the need to hold the key down manually for continuous input.

A long press will trigger the assigned function normally.

Performance Settings

Polling Rate

Polling rate determines how frequently the keyboard reports input data to the computer. A higher polling rate can reduce theoretical input latency but may also increase system resource usage.

The Jet 75 supports the following polling rates:

• 1,000 Hz
• 2,000 Hz
• 4,000 Hz
• 8,000 Hz

Berserk Mode

When Berserk Mode is enabled and supported by the current performance configuration, Rapid Trigger sensitivity can be set to:

• 0.01 mm
• 0.005 mm
• 0.001 mm

Adaptive Dynamic Calibration

We recommend keeping Adaptive Dynamic Calibration enabled.

When enabled, normal key presses help the keyboard continuously refine its calibration data. As more keys are used, the calibration can become more accurate.

If the magnetic switches have not been replaced, manual calibration is usually not required.

Win Key Lock

Win Key Lock prevents accidental presses of the Windows key during gaming or typing. You can also press Fn + Win to quickly lock the Windows key.

This feature does not apply to macOS.

Stability Mode

Stability Mode enables an optimization algorithm designed to improve keyboard stability when using extremely sensitive trigger parameters.

Other Settings

• Check and update the keyboard firmware version.
• Use one-click factory reset to restore all keyboard settings.
