h move the cursor one space to the left
j move the cursor one space down
k move the cursor one space up
l move the cursor one space to the right
These commands may be repeated by holding the key down. Try moving around in your text now. If you attempt an impossible movement, e.g., pressing the letter k when the cursor is on the top line, the screen will flash, or the terminal will beep. Don't worry, it won't bite, and your file will not be harmed.
