IBM 3270 Operator's Manual page 90

If you key an incorrect accent, press the RESET key to cancel the Dead Key
operation and then replace the accent (at the cursor location) with the correct
accent.
If your second keystroke is not a valid letter or a space, a Do Not Enter-
"Accent Plus What" ()(
*' +?,)( *' +? ,)( *"'+?,)( *"+?,
or
)( *
J
+? )
message appears in the Operator Information Area, and a stand-
alone accent is displayed at the cursor location. To recover from this error,
press the RESET key and then rekey both the accent and a valid letter (or
space).
If the Do Not Enter-What (
X?+ )
message appears in the Operator Infor-
mation Area during a Dead Key operation, either (1) you have taken an illegal
action or (2) the host system has interrupted your operation. Press the RESET
key, check the contents of your screen, and then rekey the accent and the
letter again.
By now you should be quite familiar with your display station. If there
is any area that you are still not sure about, turn back and reread the
section that discusses it. Press the key or keys in question, and watch
the result. If you still have questions, now is the time to get them answered.
Ask the appropriate person in your organization for an explanation.
