Undeleting Text
Text deleted with the Del or BkSp key can be restored at the cursor
location as long as the cursor has not moved to another line. (Once
the cursor is moved using the arrow keys the text is lost and cannot
be recovered.) To undelete the removed text, press the F4 key. Text
removed using F7 (clear to end of line) cannot be recovered.
Lines deleted using the F8 key can be pasted back anywhere in the
document by pressing the F3 key.
Working With Blocks of Text
To mark a section of text as a block, press F2, the mark command,
and use the arrow keys to block the text. Blocked text is displayed in
reverse video.
Blocks of text can be cut (saved in a scratch buffer), pasted (copied
from the scratch buffer to the current cursor location), or sent to a
line printer.
To cut a block of text once it has been marked, press F6, the cut
command key. The text is saved in a buffer and removed from the
screen. The text to the right of the block is shifted to the left.
To paste a block of text from the scratch buffer, position the cursor
where the text should be inserted and press F1, the paste key.
To print a block of text press F5, the print key, while the block is
marked. The marked text is sent to the printer.
To copy a block of text, fi rst mark it, then cut it, then paste it back in
the original position. Now you can move the cursor to where you
want the block copied and paste it again.
Saving and Exiting
To exit the Text Editor, press Esc. The program asks you if the current
text should be saved:
Save Changes [Y/N]?
At this point, if an N is pressed, the program exits without saving
the text. If a Y is pressed, you are asked to enter a fi lename. If the
fi le already has a name, the name is shown on the screen. Use the
backspace key to delete or modify the name. Pressing ENTER
instructs the program to save the text in a fi le with the name
specifi ed and exit. The Esc key can be used at any time to abort the
exit command.
❖ Note: You cannot edit fi les on the A: drive.
