Note: The following discussion is based on the default key assignments for these keys.
With the system default setting, the end-user can only use the cursor keys to move from item to item in the order in which the items are processed. For example, pressing the Down Arrow key moves the cursor to the next field on the form, not to the field below the current field.
Mouse: The mouse can be used to move to any field at any time, regardless of whether free-form cursor movement is enabled.
When free-form cursor movement is enabled by setting CURSORFREE to ON, the Up Arrow and Down Arrow keys move vertically through form fields. As in the default setting, Enter and Tab move to the next item in the processing order, and Shift-Tab moves to the previous field. Note that the CURSORFREE option does not enable the use of the Right arrow and Left arrow to move horizontally among fields.
The CURSORCROSS option allows something quite different. When CURSORCROSS is OFF, the Left Arrow and Right Arrow keys move the cursor within the current field, but do not move the cursor from field to field. Thus, if the user is in the first position of a field and presses the Left Arrow key, the cursor does not move. When CURSORCROSS is ON, the Left Arrow and Right Arrow keys can move the cursor from field to field. Pressing the Right Arrow key while on the last position moves the user to the next item. Pressing the Left Arrow key while on the first position moves the user to the previous item.
