The highlighted keys (in the center) are described with the associated functions
after this figure.
The character backspace function (activated by pressing the Character
Backspace key) moves the cursor back to the previous position in which data
can be entered.
If the cursor is in the first position of an input field, it moves back to the last
position of the preceding input field.
The field advance function (activated by pressing the Field Advance key) moves
the cursor to the first position of the next input field.
The field exit function (activated by pressing the Field Exit key) causes the
cursor to exit an input field, and null characters (displayed as blank) are
inserted from the current cursor location to the end of the field.
When you press the Field Exit key in a right-adjust field, the data to the left of the
cursor is shifted to the right. The vacated pOSitions are filled with zeros or
blanks as specified by the program, and the cursor advances to the next input
field.
