^ Chapter 3. Using the Entry Assist Capabilities
This chapter lists the Entry Assist capabilities and tells you how to use them.
Turning On Entry Assist
The DOC ON OFF key turns all the Entry Assist functions on and off.i
I When you first turn on the power to a display unit after the control unit (3174) has
I been powered on or restarted, the Entry Assist functions are turned off.
j To turn on the Entry Assist functions, press the DOC ON OFF key. This puts the
display in "document mode" and causes either the DOC or the D-> symbol to be
displayed in the operator information area (column positions 66-68).
If you have Entry Assist on when you turn the power off your display unit, Entry
I Assist is still in effect when power comes back on with Configuration Support B
i Release 2 or later code. Prior to Release 82, the Entry Assist function is always off
whenever a display unit is powered on. Ask your system administrator which
configuration your control unit is using. If the controller is restarted, then you need
, to turn Entry Assist on.
The D-> symbol is displayed when both "document mode" and enhanced
null/space processing mode^ are active. The DOC symbol is displayed when only
I "document mode" is active.
To turn off the Entry Assist functions, press the DOC ON OFF key while in document
mode. This also clears the DOC symbol (or restores the if enhanced
! null/space processing mode is active).
Using the Formatting Controls
This section lists the formatting controls and explains how to use them.
The Change Format Key
To put your display in change format mode:
1. If you have not entered your display into "document mode," do so at this time.
2. Then press the Change Format (CHG FMT) key.
This action places the display in "change format" mode. You can use the keyboard
controls to set and clear margins, tabs, and the audible "end of line" signal only
when the display is in change format mode. If an invalid keystroke is pressed, it
may be necessary to press the reset key before further keystrokes will be
accepted. Use the change format active keys shown in Figures 3-1 through 3-6 on
the following pages.

extended-select mode.
