Using Codex often means moving back and forth between your keyboard, mouse, active threads, approval requests, navigation controls, and message box.
DarkBeacon Codex Mode brings those controls onto the keyboard.
Codex Mode is currently a dedicated feature exclusive to Devil Breaker Print Codex . When enabled through DarkBeacon.AI, Print Codex switches into its dedicated Codex device mode, allowing selected keys to control supported Codex actions directly.
You can manage up to six Agent threads, see their status through RGB lighting, approve or reject requests, fork conversations, navigate Codex, dictate prompts, and send messages directly from the keyboard.
When Codex Mode is turned off, Print Codex returns to its regular keyboard mode, while your saved Codex mappings remain available for the next time you enable it.

FAQ
What Is Codex Mode?
Codex Mode is a dedicated operating mode built into Devil Breaker Print Codex that turns selected keyboard controls into physical controls for your Codex workflow.
Currently, Codex Mode is exclusive to Devil Breaker Print Codex within the DarkBeacon keyboard lineup.
In its regular mode, Print Codex works as a one-handed TMR magnetic keyboard with features including:
- 0.001 mm TMR sensing precision
- Adjustable actuation
- Rapid Trigger
- Key remapping
- Advanced key functions
- Macros
- RGB lighting
- Gamepad Mode
Codex Mode gives the same physical keyboard a second role.
Once enabled, assigned keys use the dedicated Codex control channel instead of their regular keyboard functions. Keys that have not been assigned a Codex action can continue to work as normal keyboard inputs.
This allows Print Codex to become a dedicated left-hand Codex control surface while your right hand stays on your mouse, trackpad, primary keyboard, or editor.
How to Enable Codex Mode
Before getting started, make sure you have:
- Devil Breaker Print Codex connected via USB
- DarkBeacon.AI installed
- The ChatGPT desktop app installed and signed in
1. Open DarkBeacon.AI
Go to Device Center and select Devil Breaker Print Codex.
2. Open Codex Mode
Select Codex Mode from the device menu.
3. Enable Codex Mode
Turn on Enable Codex Mode.
The keyboard will briefly disconnect and automatically reconnect. This is normal because the device is switching operating identities.
Switching Codex Mode on or off does not erase your saved Codex mappings.
4. Configure Your Controls
Select a key on the keyboard layout and assign the Codex control you want, or drag a Codex control directly onto a key.
When you are finished, click Save to Keyboard.
19 Codex Actions. Map Them Your Way.
Codex Mode gives Print Codex access to 19 mappable Codex actions, covering Agent threads, navigation, approvals, voice input, and other frequently used interactions.
You decide where those controls live on the keyboard.
A single Codex value can also be assigned to multiple physical keys, allowing you to build the layout around the way you actually work instead of following one fixed configuration.
Control Up to Six Agent Threads
Codex Mode includes six Agent controls designed to correspond to different Codex threads.
Each Agent control can use RGB lighting to show its current status at a glance.
| RGB Indicator | Agent Status |
|---|---|
| White | Idle |
| Blue | Thinking |
| Green | Complete |
| Orange | Input Needed |
| Red | Error |
| Off | No Thread Assigned |
Single Press
Press an Agent key once to focus its assigned thread in the background.
This lets you interact with the selected thread without necessarily bringing the Codex window to the front.
Double Press
Double-press an Agent key to bring the ChatGPT desktop app forward and focus directly on that conversation.
When several Codex tasks are running at once, the RGB indicators help you see which thread is idle, thinking, finished, waiting for input, or reporting an error.
Approve. Reject. Fork. Keep Moving.
Codex workflows often pause at small decision points. Print Codex puts several frequently used Codex controls directly onto the keyboard.
| Control | Action |
|---|---|
| APPR | Approve the Agent's current proposal or approval request. |
| REJ | Reject the current proposal or approval request. |
| FORK | Fork the current conversation into a new thread while preserving its context. |
| FAST | Toggle Fast Mode in the current workflow. |
| CODEX | Send the message currently entered in the compose field. |
The goal is simple: reduce the small interruptions that repeatedly move your hand away from the rest of your workflow.
Navigate Codex From the Keyboard
Codex Mode can also use Print Codex's physical control knob and directional controls for navigation.
Control Knob
- Rotate Left: Move to the previous control or option.
- Rotate Right: Move to the next control or option.
- Press: Open or select the highlighted control.
- Press and Hold: Open Codex Micro settings.
Direction Controls
- Up: Switch planning mode.
- Down: Toggle the sidebar.
- Left: Go back.
- Right: Go forward.
These controls give your left hand another way to move through Codex without repeatedly reaching for the mouse.
Speak Your Prompt
Print Codex also supports microphone controls for voice input in Codex Mode.
Press and Hold MIC
Hold MIC while speaking and release the key when you are finished.
Continuous Recording
Double-press MIC to begin continuous recording. Press it again to stop.
Voice input is captured and transcribed through the desktop client.
For users who prefer describing a task instead of typing a longer prompt, voice input provides another way to interact with Codex while keeping the workflow moving.
How Codex Key Mapping Works
DarkBeacon.AI gives you two ways to assign Codex controls to Print Codex.
Method 1: Select a Key
Select a physical key on the keyboard layout, then choose the Codex value you want to assign.
Method 2: Drag and Drop
Drag a Codex control directly onto the desired physical key.
Mapping Rules
- One key holds one assigned value. Assigning a new value to that key replaces the previous one.
- One value can be assigned to multiple keys. For example, you can assign APPR to more than one physical key.
- Controls are not restricted to their original physical group. Knob or directional values can also be assigned to regular keys where supported.
- Right-click to clear an assignment. You can also use the clear control to reset the full mapping.
After configuring your layout, always click Save to Keyboard.
Important: The Keycap Is Not the Command
There is one important concept to understand when using the Print Codex keycap set:
The label printed on a keycap and the actual Codex command are not necessarily the same thing.
Labels such as FAST, APPR, REJ, and FORK are visual labels for command slots.
The actual action associated with each command slot is configured through the Codex desktop environment, while DarkBeacon.AI determines where that Codex value is assigned on the physical keyboard.
In other words, the printed keycap does not permanently lock that physical key to only one Codex command.
Is It Still a Keyboard in Codex Mode?
Yes.
Keys that have not been assigned to a Codex action continue to work as normal keyboard inputs.
Only assigned keys use the Codex control channel.
This lets Print Codex combine standard keyboard input with dedicated Codex controls inside the same physical device.
Codex Mode vs. Regular Keyboard Mode
Print Codex can switch between two different operating workflows.
| Feature | Regular Mode | Codex Mode |
|---|---|---|
| Standard Keyboard Input | Active | Active on Unassigned Keys |
| Codex Mappings | Inactive | Active |
| Rapid Trigger | Active | Inactive |
| Advanced Key Functions | Active | Inactive |
| Standard Key Remapping | Active | Inactive |
| Macros | Active | Inactive |
| Saved Codex Mapping | Retained | Active |
While Codex Mode is enabled, Codex mappings take priority.
Rapid Trigger, advanced key functions, standard key remapping, and macros do not trigger during Codex Mode.
Turn Codex Mode off and those regular keyboard functions become active again. Your saved Codex configuration remains available for the next time you enable it.
Who Is Codex Mode For?
Developers Working With Codex
Put frequently used approvals and Codex controls within reach instead of repeatedly moving between keyboard and mouse.
Users Running Multiple Threads
Six Agent controls let you move between multiple Codex conversations while RGB feedback shows their status at a glance.
Long-Running Agent Tasks
When a task takes time to complete, Agent status indicators can help show whether it is still thinking, complete, waiting for input, or reporting an error.
Voice-First Workflows
MIC controls let you dictate prompts when speaking is more convenient than typing.
Left-Hand Keyboard + Right-Hand Mouse Workflows
This is where the one-handed design becomes especially useful.
Keep Print Codex under your left hand while your right hand stays on your mouse, trackpad, primary keyboard, or editor.
Codex on the left. Everything else on the right.
Why Put Codex Controls on a Physical Keyboard?
Agent-based workflows introduce more states to manage.
A thread can be thinking, waiting for input, complete, or reporting an error. At the same time, you may need to approve a request, reject a proposal, switch threads, navigate the interface, dictate a prompt, or send a message.
Physical controls give those repeated interactions a dedicated place outside the screen.
With Print Codex, RGB lighting can communicate Agent status while mapped keys place frequently used Codex interactions under your fingertips.
Instead of replacing the Codex interface, Codex Mode is designed to make interacting with it more direct.
Codex on the Left. Everything Else on the Right.
Devil Breaker Print Codex combines two workflows inside one device.
With Codex Mode disabled, it operates as a Devil Breaker TMR magnetic keyboard with adjustable actuation, Rapid Trigger, advanced key functions, macros, remapping, RGB controls, and other standard features.
With Codex Mode enabled, selected keys become dedicated controls for your Codex workflow.
Switch threads. Check Agent status. Approve changes. Reject requests. Fork conversations. Navigate. Dictate. Send.
Codex at your fingertips.
