Key assignments and macros

The official software manual documents a Main layer and an FN1 layer. It does not describe separate named profiles.

Programming keys

Open the keyboard section in the software. A key can be assigned to one of the following categories:

• Keyboard - standard keyboard functions.
• Mouse - mouse functions assigned to a keyboard key.
• Multimedia - media shortcuts such as volume and play/pause.
• Macro - a macro previously created in the macro editor.
• Commands - system commands such as Show Desktop or Task Manager.
• Key combination - a custom shortcut using Ctrl, Windows, Alt or Shift.

Choose whether you want to program the Main layer or the FN1 layer. Functions on the Main layer work by pressing the key directly. Functions on the FN1 layer work only while holding the Fn key.

1. Select the key you want to program.
2. Choose the required function.
3. Click the Save icon.
4. Assigned keys are shown in blue.
5. To reset a key, select it, use the Reset icon and save the configuration again.

Lighting customisation in the software

Open the LED section to select an effect and, where available, adjust its speed, brightness and colour. Select a single colour or enable the colourful RGB option, then click Save.

To customise individual keys, select Custom, choose a colour and click the keys you want to change. Multiple keys can be selected by holding the mouse button and dragging across them. Click Save when finished.

Creating and assigning a macro

1. Open the macro editor using the </> icon.
2. Create a new macro, enter a name and confirm it.
3. Click Record and enter the required key sequence.
4. Adjust the delays in milliseconds if the macro needs to run faster or slower.

6. Return to the keyboard section and assign the saved macro to the required key.

The Xyra has hot-swappable switch sockets and supports both 3-pin and 5-pin mechanical switches.

Yes. Normal keyboard use and the built-in Fn shortcuts work without the software. Install the software for advanced key assignments, macros and detailed RGB customisation.

Which replacement switches are compatible?

How do I lock the Windows key while gaming?

Press Fn + Windows to lock the Windows key. Press the same combination again to unlock it.

Should I select ANSI or ISO during software installation?

How do I assign a macro to a key?

Create and save the macro in the macro editor. Then return to the keyboard section, select a key, choose Macro and assign the saved macro.
