About this app

An on-screen keyboard, trackpad, media buttons and shortcuts on the bottom screen for dual-display handhelds - tested on the AYN Thor.

Tested with: RetroArch, Moonlight PC Streaming, Musicolet, VLC.

Notes & usage tips:
- If inputs are not detected, press the "Input Focus" button.
- In RetroArch, press "Scroll Lock" to toggle "Game Focus":
Game Focus ON: Inputs are sent directly to the emulated system - you can type text, but RetroArch hotkeys won't work.
Game Focus OFF: RetroArch hotkeys work, but typing text will trigger default hotkeys.

The trackpad is not a standard trackpad. It is designed specifically for mouse emulation in RetroArch, tested with DOSBox Pure, and also works with Moonlight PC Streaming.

Multiple layouts: US Windows keyboard, Numpad, Thomson MO5, Commodore 64, RetroArch shortcuts, Music media buttons, Video shortcuts, Trackpad.

19 themes colors included.

Ratings and reviews

Works very well, does what I need it to do, features that I would find helpful: 1. The ability to simplify the keyboard. - I have big fingers and I'd like to remove a shift from the keyboard to be easier to type. 2. The retroarch pad made me realize there are plenty of additional keys I'd like bound to the quick pad menu. 3. Rotate the trackpad. - Found myself reading manga and turning my Ayn Thor to vertical to read, and using the mouse to zoom and pane. controls are currently inverted.

Superb, I really like it. The trackpad is the killer feature. Hopefully can get it to fake a mouse even better with updates, so that the pointer can be seen while browsing the web. Other software can be limiting, e.g. GameHub Lite doesn't work with a real mouse, and the simulated touch here means that small moves are sometimes treated as a click. But in general, this keyboard lets me play some slower pace mouse-only games, and for that I am grateful.

Good idea, poor execution. Useful for niche cases (like Winlator on AYN Thor), but flawed. The QWERTY keyboard is cramped and error-prone, making typing frustrating. No customization is a major issue—too many unnecessary keys and risky layout choices (especially in RetroArch). Let users adjust keys; current setup feels awkward and unreliable.

What’s new

- New layout: Scaled Trackpad with mouse buttons.
The old trackpad is still available but you should disable it in the settings.
Sometimes the scale of the trackpad is wrong. Press the "-" button then "+".
