y = 2,
text = "Right-click anywhere!",
foreground = colors.yellow
})

-- Create a ContextMenu
local contextMenu = main:addContextMenu({
x = 10,
y = 5,
background = colors.black,
foreground = colors.white,
})

contextMenu:setItems({
{
label = "Copy",
onClick = function()
statusLabel:setText("Action: Copy")
end
},
