8. User Tips
- Spanish 'Ñ' Key: The keyboard features a UK language layout. If you require the 'Ñ' key for Spanish, you may need to configure your operating system's keyboard input settings to a Spanish layout. This will map the 'Ñ' character to an existing physical key, typically the semicolon/colon key or another designated key depending on the specific Spanish layout chosen.
- Membrane Keyboard: The TK100 uses membrane switches, which offer a quieter typing experience compared to mechanical keyboards. This is ideal for office environments or users who prefer a softer key press.
- Battery Life: While the keyboard has a 2000 mAh battery, extensive use of RGB lighting will consume more power. To maximize battery life, consider adjusting the brightness or turning off the RGB lighting when not needed.
- Switching Devices: Utilize the BT1 and BT2 modes to quickly switch between two paired Bluetooth devices without needing to re-pair each time.
