Trackpad4Game

Play games on a laptop touchpad: keys become mouse buttons.

Keys as mouse buttons. V and B act as left and right click; holding the key holds the button, so mining in Minecraft works.
No stray taps. The touchpad's own clicks and taps are blocked while it is on; the pointer, the taskbar and the tray still work.
Pointer keeps moving. Palm rejection is turned off while it is on, so you can aim while holding keys. Your own setting comes back afterwards.
Only in your game. Optionally acts only while Minecraft (Java or Bedrock) or another game you pick is in front.
One toggle. Press the backtick key in your game, or use the switch in the tray panel. A small badge shows on or off.

No install needed.

Features

Mouse buttons on keys: V is the left button and B the right; holding a key holds the button. Click a key in the panel and press a new one to change it.
Touchpad blocking: The touchpad's clicks and taps are blocked while it is on, so a stray tap doesn't attack or place a block. Moving the pointer still works, and the taskbar and tray stay clickable.
Pointer keeps moving: Windows pauses the pointer for a moment after each key press (palm rejection). While trackpad4game is on, that pause is turned off, so you can aim while holding V, B or W/A/S/D. Your own touchpad setting is put back afterwards. Windows 11 with a precision touchpad.
Game only: Optionally acts only while one of your games is the active window (Minecraft Java and Bedrock by default); everywhere else the keys and touchpad behave normally. Open a game, then click the tray icon to add it.
On and off: Press the backtick key, or use the switch in the tray panel. A short sound and a small on-screen badge show the state, and the tray icon lights up when it is on.
Tips: While it is on, the game no longer sees the click keys, so pick other keys if the game uses V or B. Turn blocking off if you plug in a mouse. Games running as administrator need trackpad4game run as administrator too.

Windows: Put trackpad4game.exe in its own folder and run it; to update, replace the old exe (your settings are kept). SmartScreen may warn because the exe is not code-signed. Windows 10 or 11, nothing else to install.
