The ESCape key functions are described briefly in Table 3-2.
ESCape functions are a key sequence of the ESCape key and one other key. To
use any of the ESCape functions, press the ESCape key, release it, and then press
the other key. Be sure to release the ESCape key before you press the second key.

automatic insert mode, screen window settings, scrolling on and off, and screen
display-size reduction. The other escape functions execute only once; to repeat
