Reset; Insert; Delete - IBM 3180 1 User Manual

Reset
The Reset key is used to recover from X (do not enter)
conditions. Pressing the Reset key restores the keyboard
and turns off the do not enter message for all do not enter
conditions except X X X
X o-iR . and X ^ (the Reset key has no effect
when any of these messages are displayed).
The Reset key will not operate when your display station
is sending data to, or receiving data from, the system.
Pressing the Reset key during an Ident (print ident) key
operation, causes the Ident key operation to end. The
cursor reappears on the screen, and the old printer ID or
printer class number is displayed in the operator
information area.
The Reset key can also be used to terminate an insert
mode operation.
The Dv Cnl (device cancel) key, with an Alt key held
down, is used to recover from a X (do not enter)
condition that is caused by a print key operation.
The Dv Cnl key can also be used to delete key strokes
that were saved in Record operations. This use of the Dv
Cnl key is described later in this chapter under Record
and Play.
Insert
The purpose of the Insert key is to allow you to insert a
character or characters into the middle of an input field
without changing the characters that are already
displayed there. Pressing the Insert key places the
keyboard In the insert mode of operation. The insert
mode symbol ( a ) appears in the operator information
area to remind you that your keyboard is in insert mode.
All the keyboard control keys perform normally when in
insert mode.
Delete
Pressing the Delete key when the cursor is located In an
input field deletes the character occupying the position
underlined by the cursor. It erases the character without
leaving a blank. All characters In the field to the right of
that position (and on the same line) are then shifted left
one position. The Delete key is typematic, so If held
down, each character that is shifted left to the cursor will
be deleted until the key Is released.
