Section 4. Operational Considerations
Users should be aware that it takes only a keystroke to enter or exit
document mode. Thus, users who can take advantage of Entry
Assist some of the time but must avoid it at other times will find it
easy to do so .
4.1 Selective Use of Entry Assist Capabilities
Users should be aware that the Entry Assist capabilities can be used
selectively. Thus, many users who are not working with one of the
host editors may still find it useful to operate with document mode
on. For example, with default margins set at columns 1 and 80, with
word wrap off, and with no tab stops set, operation is quite similar
to non-document-mode operation; however, the following
capabilities are still available:
Move cursor by word
• Cursor position indicator
• Delete word
• Typematic delete character
• Line ending warning signal
• Backspace delete while in insert mode.
4.2 Entry Assist/Host Editor/Formatter Considerations
and Limitations
When using a full-screen editor which uses a line command field, set
the margin to prevent inadvertent entry of data into the line
command field.
If
the line command field is to the left, set the left
margin in the first entry position to the right of the command field.
If the line command field is to the right, set the right margin just to
the left of the command field. In general, the editors indicate the
area where data entry is to occur.
