c.
This will move the cursor up or down one line on the screen,
without affecting anything displayed on the screen. Unshiftedt the
cursor moves downT and if you hotd down the l-/(jfSvl (or the
key) the cursor moves up.

This causes the cursor to move one space sideways. Unshifted,
the move is to the right; and shifted, 1he cursor moves left. All

one line down, to the left edge, if you move to the left edge the
cursor wraps to the right side of the next line up (except from the
home position).
e.
RETURN
The primary purpose of this key is to "enter" an instruction,

the next fine and the left edge of the screen but does not aftect the
line or instruction—SHIFT RETURN is a fast method for moving the
cursor down the screen,
