3. Charging your keyboard

You can charge the keyboard halves independently using the provided USB-C Cable.
NOTE:Only use your PC’s USB-A ports for charging. Using a wall brick, docking station with external power or monitor port might cause damage to your keyboard, harm the battery or even brick your device. Some of the afromentioned power sources might briefly give too much voltage and damage the charging circuit, the processor and/or battery.

4. Trackpad Gestures

Your keyboard comes with an integrated trackpad that supports various gestures:

• Click: Press the trackpad once quickly (on default 150ms tap time) to trigger Left mouse button.
• Two finger-click: Press the trackpad once quickly with two fingers to trigger Right mouse button.
• Triple-click: Press the trackpad once quickly with three fingers to trigger a Middle click.
• Scroll: Place two fingers on the trackpad and move them up or down to scroll.

Zoom functionality will be added in a future firmware update. Current development version of the pinch to zoom gesture is too unreliable right now to implement. ETA for this is july/august 2023.

You can change the trackpad sensitivity by pressing down FN and turning the left encoder. You can see the sensitivity value update on the right side display.
