PREVIOUS SCREEN

  Scrolls vertically to show the previous screen's worth of text, if any---
  roughly, the length of the current window.

  Key:   EVE default        VT100 keypad
         ---------------------------------------
         PREV SCREEN        PERIOD on the keypad

  Usage notes:

  o  If the cursor is free (default setting), it moves up in the same column
     on the screen regardless of whether text is there or not. Conceptually,
     the cursor remains in the same position on the screen while the buffer
     scrolls up.

  o  If the cursor is bound, it moves up to the corresponding line position,
     depending on the shape of your text (as with EDT, WPS, and other
     editors).

  o  For continuous movement, you can hold down or repeat PREV SCREEEN until
     you reach the top of the buffer. PREVIOUS SCREEN does not move the
     cursor across window boundaries (if you use more than one window in
     EVE). To move between windows, use the PREVIOUS WINDOW command.

  o  The EDT keypad redefines the PREV SCREEN key on the mini keypad to
     scroll 75% of the window size.
