That is correct. Note that having support for more annotation is not
technically difficult, but it's not clear what a good design would be.
For the purpose you describe, I typically do something like
levelplot(volcano, colorkey = list(space = "top"),
main = "Height (cm)")
But I don't know how to do this nicely with a vertical color key.
