The first step in using a data entry form is learning how to move the cursor. When form is first invoked, the cursor is located in the lower left corner of the display. Pressing either the QUERY <F2> button, or the ADD <F6> button, moves the cursor to the start of the upper leftmost field.
The LEFT and RIGHT arrow keys move the cursor left and right respectively within a single field. Pressing the LEFT arrow key when the cursor is at the start of a field moves the cursor to the end of the previous field. Pressing the RIGHT arrow key when the cursor is at the end of a field moves the cursor to the start of the next field.
The UP and DOWN arrow keys are used to move the cursor between fields. Pressing the Up arrow key moves the cursor to the start of the previous field. Pressing the DOWN arrow key moves the cursor to the start of the next field. The TAB key can also be used like the DOWN arrow key. Pressing the TAB key moves the cursor to the start of the next field.
Pressing the HOME key moves the cursor to the upper leftmost field on the screen. For keyboards that lack an actual HOME key, Pressing the GOLD <F1> key and then the UP arrow key, performs the same function as the HOME key.
Up to now, the cursor movement keys have been non-destructive. That is, using the given keys to move the cursor does not change the contents of the current field. The RETURN key and the LINE FEED key can be used like the DOWN arrow key, but they may change the contents of the current field (more on this later). The BACKSPACE key changes the character before the cursor to a space and moves the cursor left one position. Typing regular text (letters, numbers, punctuation, etc.) replaces the charater at the cursor with the typed key and moves the cursor right one position.
