* **Layout and Features**: These keyboards include the alphanumeric keys and the number row but typically omit the function row, navigation cluster, and numpad.
* **Advantages**:
  * **Dedicated Number Row**: Ideal for users who frequently input numbers, such as FPS gamers or data entry professionals.
  * **Compact Size**: Saves desk space while retaining essential keys.
* **Considerations**:
  * **Function Access**: May require function layers to access missing keys like arrows or function keys.
  * **Learning Curve**: Adjusting to function layers can take time.

* **Layout and Features**: These compact keyboards omit the number row, and the keys are at a more reachable distance.
* **Advantages**:
  * **Portability**: Their small size makes them easy to transport.
  * **Ergonomics**: Reduces finger travel distance, minimizing strain.
* **Considerations**:
  * **Layering System**: Extensive use of layers is necessary to access omitted keys, which can be challenging for some users.
  * **Adaptation Period**: Users may experience a learning curve when adjusting to the layering system.

## 30% Split Keyboards

*Example: Corne 5-column (36 keys)*

* **Layout and Features**: These minimalist keyboards have around 36 keys, all keys are in reachable distance, no contortions.
* **Advantages**:
  * **Minimal Finger Movement**: All keys are within easy reach, enhancing typing speed and comfort.
  * **Customization**: Highly customizable layouts to suit individual needs.
* **Considerations**:
  * **Steep Learning Curve**: Significant adjustment period due to heavy reliance on layers and key combinations.
  * **Limited Default Functionality**: May not be suitable for tasks requiring extensive use of function keys or numbers without customization.
