CTRL+D - Divide Screen
Displays two different parts of an item on the screen at the same time.
Command
CTRL+D
Action
Pressing CTRL+D allows you to view another part of the current item on the screen. A second window is created at the bottom half of the screen. When you press CTRL+D, the Status/Command Line prompts:
Starting line# for window:
Enter the line number of the first line to be displayed in the window. The upper part of the screen remains unchanged.
Example
Assume that the screen is currently displaying lines 55 to 77. Press CTRL+D
and type 100 at the Starting line# for window:
prompt. The screen continues to display lines 55 through 66 in the upper window
and displays lines 100 to 109 in the lower window. The original and resulting
screens are shown below.
