How do I type a string input into a Dashboard?

I am sure that I can handle the background. How do I type a string in thru the Dashboard?
i.e.: "the rain song by led zepplin"

It makes sense to me.

Don't know if it is what you are looking for but you can choose a "variable string" as template for the tile.

That was it, thank you.
