Back Tab Key - IBM 3270 Operator's Manual

Figure 13. The Tab key moves the cursor to the next input field.
Pressing the Tab key moves the cursor to the first character
location on line 1 if the screen is not formatted or if there are no
unprotected data fields. Tab also has typamatic capability that
allows you to move the cursor quickly from field to field.
The Back Tab key moves the cursor back to the first character
position in an input field. In the top example in Figure 14, when
Back Tab is pressed, the cursor moves from the end of the
"ADD R ESS" field (Iocation 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 if 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 14.
