Center Mouse Cursor with Hotkey

This Lua script for Rebind hardware moves the mouse cursor to the center of your screen when a hotkey is pressed. It uses the HID and System SDK functions to get screen dimensions and move the cursor.

Question

Create a key that will move the mouse to the center of the current monitor.

Rebind AI

luau

-- rebind: name=Center Mouse

local cfg = UI.Schema({
    hotkey = UI.Keybind("F6", { label = "Center Mouse Hotkey" }),
})

Bind(cfg.hotkey, function()
    local w, h = System.Screen()
    HID.MoveTo(math.floor(w / 2), math.floor(h / 2))
    return false
end)

This script moves the mouse to the center of your primary monitor when you press the hotkey.

How it works:

System.Screen() gets the primary display width and height
HID.MoveTo(x, y) moves the cursor to an absolute position using relative movements (which is how the Rebind hardware works)
math.floor() rounds to whole pixels
return false blocks the key so it doesn't reach your PC

You can customize the hotkey in the UI settings panel.
