In Microsoft Word, which function key is used to update a selected field such as a table of contents or page number?

Introduction / Context:
This question tests knowledge of function key shortcuts in Microsoft Word. Fields such as automatic page numbers, dates, or tables of contents are dynamic elements that can be updated with a single command. Knowing which function key triggers an update saves time when working with long or frequently edited documents.

Given Data / Assumptions:

• The context is Microsoft Word or a similar word processor.
• The object to be updated is a field, such as a table of contents or page number.

Concept / Approach:
In Microsoft Word, selecting a field and pressing F9 causes Word to update that field. For example, after editing headings in a document, selecting the table of contents and pressing F9 updates it to reflect the latest changes. Similarly, other fields like date or cross references can be refreshed with F9. The other function keys in the options have different purposes and are not used specifically for field updating.

Step-by-Step Solution:
Step 1: Recall from practice or study that F9 is the standard key for updating fields in Word. Step 2: Compare with F11, which is generally associated with moving between fields in some contexts but not the main update command in typical exam material. Step 3: Compare with F12, which is widely used as a shortcut for Save As in many versions of Word, not for updating fields. Step 4: Compare with F6, which is used to move focus between panes within Word, such as between the document and task panes, and again is not the field update key.

Verification / Alternative check:
You can verify the shortcut by creating a simple document in Word, inserting a field such as a date or a table of contents, and then pressing F9 while the field is selected. You should see it refresh its content. The Word help documentation and many training guides also state that F9 updates selected fields, reinforcing this as the correct answer.

Why Other Options Are Wrong:
F11: This is wrong because F11 is associated with other navigation or macro support functions and is not used as the primary field update key in basic training material.
F12: This is wrong because F12 typically triggers Save As in Word and is not related to updating fields.
F6: This is wrong because F6 shifts focus between different panes or panels in the Word interface, not for updating field content.

Common Pitfalls:
Many users update fields by right clicking and choosing update field from the context menu, and therefore do not memorise the F9 shortcut. Another pitfall is confusing F9 with other function keys that may be used in web browsers or integrated development environments. To avoid confusion, remember that F9 in Word is closely tied to field updates, especially for tables of contents.

Final Answer:
The function key used to update a selected field in Microsoft Word is F9.
