Drag the document from its location to the Trash.
The document isn’t deleted from your computer until you empty Trash.
If you don’t want to keep a document you haven’t saved yet, close the document, then click Delete in the save dialog that appears.
If you open an existing document, edit it, then decide you don’t want to keep any of your changes, you can revert the document to how it was when you opened it.
