Code:

-- 1. Define the event function
function CheckListBox1KeyDown(sender, key)
    -- Check if the pressed key is the Enter key (VK_RETURN)
    if key == VK_RETURN then
        print("Enter key was pressed!")
       
        -- Run your custom logic here
        myCustomFunction()
       
        -- Return 0 to prevent the key from triggering default Windows behaviors
        return 0
    end
   
    -- Return the original key for any other button presses
    return key
end

-- 2. Bind the function to your UI element
-- (Replace 'CETrainer.CheckListBox1' with your actual form and element names)
CETrainer.CheckListBox1.OnKeyDown = CheckListBox1KeyDown


-- Your custom function to execute
function myCustomFunction()
    print("Executing custom action...")
end
