Use hammerspoon to rebind numeric keypad

-- Function to remap numpad keys to top-row keys
function remapNumpadToTopRow(padKey, topKey)
    -- Bind the numpad key with all possible modifiers
    hs.hotkey.bind({"cmd", "alt", "ctrl", "shift"}, padKey, function()
        -- Simulate pressing the top-row key with the *actual* currently pressed modifiers
        local mods = hs.eventtap.checkMouseKeys() -- A helper to get current modifiers
        hs.eventtap.keyStroke(mods, topKey)
    end)
end

-- Apply this function for each number 1-9 and 0

Start by locating the repository's Hammerspoon or Lua configuration, since no target file is named. Compare the existing setup with the provided keypad-to-top-row mapping and verify that numeric keypad keys work with the intended modifiers; done means the mappings are integrated and usable.
