## Change the Theme

The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):

```Python hl_lines="3"
{!../../../docs_src/configure_swagger_ui/tutorial002.py!}
```

That configuration would change the syntax highlighting color theme:

	l2.Remove(e2)
	checkListPointers(l2, []*(_Element[int]){e1, e3, e4})

	l2.MoveToFront(e3) // move from middle
	checkListPointers(l2, []*(_Element[int]){e3, e1, e4})

	l2.MoveToFront(e1)
	l2.MoveToBack(e3) // move from middle
	checkListPointers(l2, []*(_Element[int]){e1, e4, e3})

	l2.MoveToFront(e3) // move from back
	checkListPointers(l2, []*(_Element[int]){e3, e1, e4})

	sink64[3] = math.Copysign(-1, c)
}
