Sets/returns the shortcut key for moving to the previous field.
object.PrevField= string
Read/Write at run time and design time.
Zero-length string ("") is the default
A maximum of five keys can be set in the PrevField property. When setting multiple keys, use a comma (",") as a delimiter. There are keys that are used by Windows, such as [F10], and so on, which will not function as the user may expect if assigned to the control.
TDBDate.Key.PrevField = "^{Enter}"
In this example, focus would be moved to the previous field when [Ctrl]+[Enter] is pressed.
The PrevField and the PrevCtrl properties can be assigned with the same keys. In this case, the control determines whether moving to the previous field or the previous control, by referring to the current position of the caret. If the current position is placed within the first field, the focus will move to the previous control. Otherwise, the caret moves to the previous field.
By default, the Shift+TAB key also moves to the previous control when the control's TabAction property is set to 1-Field Navigation.
When setting the control for free format entry, all text will be treated as one field. Therefore, the key assigned to this property will not take any effect.
When moving away from a field or selected fields that are half way entered by hitting the Tab/Shift+Tab or the keys assigned to the NextField / PrevField, NextCtrl / PrevCtrl properties, the incomplete values will be automatically rounded to the closes value. For example, with the cursor placed in the following position "1998/1|_/31", by hitting the Tab/Shift+Tab key the month field will be rounded displaying "01". "1998/0|_/31" will also be rounded to "01". Note that moving the focus away from the control will also cause the incomplete fields to be rounded accordingly.
Using the arrow combination keys and the mouse for navigation within the control will not cause automatic rounding. Also automatic rounding does not apply to fields that are empty.
