Pressing the SKIP or the Tab key moves the cursor to the first
character location on line 1 if the screen is not formatted or
there are no unprotected data fields. SKIP and Tab have
typamatic capability that allows you to move the cursor quickly
from field to field. Note that the SKIP, Tab, and New Line keys
all advance the cursor to the first character position of an
unprotected field and that, in addition, the New Line key places
the cursor in the first new line available (not having all protected
fields).
The Back Tab key moves the cursor back to the first character
position in an input field. I n the top example in Figure 23, when
Back Tab is pressed, the cursor moves from the end of the
"ADD R ESS" field (location A) to the first character location in
that field, the R in RED.
If the cursor is already in the first character position of an
input field, and you press the Back Tab key, the cursor will then
move back to the first character position of the preceding input
field. This case is shown in the lower example in Figure 23. When
the operator was about to enter the "Mfg Code" No. at location
A, it was noticed that the
IIQty
Ordered" was missing. Therefore,
the operator pressed Back Tab, which moves the cursor back to
the first character position of the
IIQty
Ordered" field.
Figure 23. The Back Tab key moves the cursor back to the beginning of an
input field.
When your screen is unformatted, the Back Tab key
repositions the cursor to the first character location on line 1.
