Use Word enumerations

Hello. I have the following Word-Interop code. How can I use the Word enumerations in this code? At the moment I am use the integer 6 which I know to be the value of wdStory in the Word object library, and even 1 for true.

using System;
using System.Text;
using Microsoft.Office.Interop.Word;

namespace ConsoleAppWord {
    class Program {

        public void ProcessDocument(Document aDoc) {

        }
        static void Main(string[] args) {
            Application wdApp = new Application();
            Document wdDoc;

            try {
                wdApp.Visible = true;
                //wdDoc = wdApp.Documents.Add();
                wdDoc = wdApp.Documents.Open("C:\\Users\\Andrew\\Documents\\Somewhere.docx");
                wdApp.Selection.EndKey(6); // wdStory
                wdApp.Selection.TypeText("Hello Word!");
                wdApp.Selection.TypeParagraph();
                wdApp.Selection.TypeParagraph();
                wdApp.Selection.TypeText("Goodbye Word!");
                wdDoc.Paragraphs[1].Range.Font.Bold = 1;
                wdDoc.SaveAs("C:\\Users\\Andrew\\Documents\\Somewhere");
                ((_Application) wdApp).Quit();  // prevent ambiguity message

            } catch (Exception ex) {
                Console.WriteLine(ex.Message);
                throw;
            } finally {
                System.Runtime.InteropServices.Marshal.ReleaseComObject(wdApp);
            }
        }
    }
}

Doh! 2 seconds after posting this I had some inspiration:

wdApp.Selection.EndKey(Unit : WdUnits.wdStory);

but I still need the value for true?
