User Guide
Input Modes
TabletPen has two input modes, selectable in Settings > Pen > Mode:
Digitizer Mode (Default)
Your pen position maps directly to your computer screen — like a Wacom tablet. Touch the top-left of your tablet, the cursor goes to the top-left of your screen.
- Best for: Drawing, painting, photo editing
- Pen pressure and tilt are sent to your computer
- The drawing area on your tablet matches your screen’s aspect ratio
Mouse Mode
Your pen moves the cursor relatively — like a trackpad. Drag your pen to move the cursor in that direction.
- Best for: General navigation, presentations, browsing
- One-finger drag moves the cursor
- Adjust speed in Settings > Trackpad > Mouse Speed
Pen Input
- Draw: Touch the pen to the tablet surface. Pressure and tilt are sent to your computer.
- Hover: Move the pen above the surface to position the cursor without clicking.
- Eraser: Flip the pen (if your stylus has an eraser end) to use the eraser tool.
- Barrel button: Press the button on your stylus for a right-click.
Touch / Trackpad Gestures
Your fingers work as a trackpad:
| Gesture | Action |
|---|---|
| One finger tap | Left click |
| One finger drag | Move cursor (mouse mode) |
| Two finger drag | Scroll |
| Two finger pinch | Zoom (Ctrl+scroll) |
| Double-tap and drag | Click-and-drag (like macOS trackpad) |
Double-tap-and-drag can be enabled in Settings > Trackpad > Double-tap-and-drag.
Device Selector
The device selector in the top-left shows your paired computers.
- Filled dot — Connected and active (HID input flowing)
- Hollow dot — Bluetooth connected, available for quick switch
- No dot, dimmed text — Paired but not reachable (out of range or powered off)
- + Pair new device — Enter pairing mode to add a new computer
Tap the selector to switch between computers. The dropdown shows the connection status of each device.
Settings
Open settings by tapping the gear icon in the toolbar.
