5. Operating Instructions
5.1 Basic Keyboard Functions
The R68 HE features a 68-key ANSI layout. Standard key functions operate as expected. Utilize the Function (Fn) key for secondary key actions, typically indicated by legends on the keycaps.
5.2 RGB Lighting Control
The keyboard features dynamic RGB backlighting and side light bars. You can control these directly from the keyboard or through the customization software.
Keyboard Backlight Controls:
- Fn + \ |: Switch Light Effects
- Fn + Enter: Switch Light Color

5.3 Magnetic Switch Features (Rapid Trigger, DKS, MT, TGL, SOCD)
The magnetic switches allow for advanced functionalities crucial for competitive gaming:
- Rapid Trigger (RT): Allows a key to activate and deactivate based on movement rather than a fixed actuation point. This means a key can register a press as soon as it moves down and reset as soon as it moves up, enabling extremely fast repeated inputs.
- Adjustable Actuation: Customize the actuation point for each key individually from 0.005mm to 3.4mm via the software, tailoring sensitivity to your preference.
- Dynamic Keystroke (DKS): Assign up to four different actions to a single key based on how far it is pressed.
- Mod Tap (MT): A key can perform one action when tapped and a different action when held.
- Toggle Key (TGL): Press and hold a key to activate a continuous action, release to stop.
- Snap Tap (SOCD - Simultaneous Opposite Cardinal Directions): Optimizes directional inputs in games by neutralizing opposing inputs (e.g., pressing both 'A' and 'D' simultaneously results in no horizontal movement).
