INTRODUCTION
In addition to entering data into a table using a form, you can also use a form to make changes to the data, just as you do in Datasheet view. Your changes to a field are saved when you move the insertion point out of that field.
TIP
Selecting an Entry
When you press Tab to move to a field, the entire entry is selected. You can start typing to replace the existing entry with a new entry.
