Position yourself about 10 spaces to the right of the word "throne" and type a letter. The editor will immediately lengthen your line with blanks so it can place your character where requested. You can delete these blanks to restore the text by pressing the backspace key or positioning yourself just past the "e" of "throne" and holding down the Del key. The Del key deletes the character at the cursor causing the line to Shift over.
In general, you will find the Backspace key useful for correcting new text being entered, while the Del key is useful for editing existing text. As an added advantage, the Del key saves each character it deletes. Position yourself at the start of a line and hold down the Del key. To restore the last deleted characters press the Ctrl and the Ins keys simultaneously. By holding this key down you can restore the last 256 characters deleted in this editor session. The characters need not be restored where they were deleted. They will be restored at the active cursor wherever it is, even at the command line. This can be a useful method of moving strings of characters.
Change the word "Eleven" to "Elven" in line 1 by moving the cursor to the second "e" and pressing the Del key. Now move to line 7 and position the cursor under the "D" in the word "Disk" and change this word to "Ring" by simply typing over it. Note that by default, you are always in replace mode.
