Actually, none of the edits you have made so far are permanent. If you wish to go back to the way the file was before you started, you can delete all your modifications with the single command: Delete Modifications (typed "dm"). Since this is usually a drastic step, you will be required to give two OKs to confirm it. Remember this command. Write it down on a piece of paper, and then go have fun with the file. When you are done, you can Delete Modifications, and you will have your original TUTOR file back. Later you will learn to make your modifications a permanent part of the file, along with a number of other things. You've done quite a bit already. Remember, to get back to the beginning of this file, the command is Jump Origina, followed by two OKs. Have fun, and when you are done, you can continue in the file named TUTOR2. You can get there now by using another kind of Jump command, which will be discussed later. For now just type "jl" (you should see "Jump (to) Link" in the command indow), and then type "tutur2," (be sure to include the final comma), and then type OK.
