The Move Cursor Down command is a relative cursor movement command. It moves the cursor
down the screen without affecting its column position.
Once the cursor enters a scrolling region the cursor cannot be moved outside the scrolling region
with a relative cursor movement command. The cursor stops at the edge of the scrolling region
and the region is not scrolled. However, if the cursor is already outside the scrolling region, the
Move Cursor Down command can move the cursor until it reaches the bottom edge of the screen.
When the cursor reaches the bottom line of the screen, the cursor cannot be moved any farther by
this command. The cursor remains on the bottom line and the screen is not scrolled when an
attempt is made to move the cursor past the bottom line.
When the cursor is moved between normal lines and double-width or double-size lines, the
cursor moves across the screen horizontally as well as vertically. This is because the cursor
follows character column positions, which are in different physical locations on the screen for
normal and double-width (or double-size) lines. (Double-width and double-size lines are 40
columns wide, and normal lines are 80 columns wide.) For example, as the cursor moves
between column 40 on a double-size line and column 40 on a normal line, the cursor’s physical
position jumps from the right margin of the screen on the double-size line to the center of the
screen on the normal line.

<ESC>[<Pn>B
<Pn> is a numeric parameter, designating the number of lines to move.
If <Pn> is 0 or omitted, the cursor moves down one line.
If <Pn> is greater than 0, the cursor moves down <Pn> lines.

scrolling region or below the bottom of the screen.

Moves the cursor down one line.
<ESC>[021B
Moves the cursor down 21 lines. If the cursor was originally less than 21 lines up from the
bottom of the screen (or scrolling region), the cursor moves to the bottom line of the screen
(or scrolling region).
