press Esc and then : (the colon). 
The cursor will go to the bottom of the screen at a colon prompt. 
Write your file by entering :w and quit by entering :q. 
You can combine these to save and exit by entering :wq. 
However, if you're finished with your file, it's generally more convenient to type Shift-z-z from command mode.
