Challenge 2: Inserting a New Figure Between Existing Captions — Solution Walkthrough

Setup: Figure 1, Figure 2, Figure 3 (all via Insert Caption). A new
image is inserted between the original Figure 1 and Figure 2, and
captioned the same way.

What happens with real Insert Caption fields:

The new image becomes "Figure 2" (since it's now the second figure in
document order), and both of the figures that used to be "Figure 2"
and "Figure 3" automatically renumber to "Figure 3" and "Figure 4"
respectively. No manual editing is needed anywhere — every caption
label updates itself to stay in correct sequential order the moment
the new caption is inserted (or the next time the document's fields
are updated, depending on Word's exact refresh timing).

What would have happened with manually-typed captions instead:

If all three original captions had been typed as plain text ("Figure
1", "Figure 2", "Figure 3" typed by hand, not inserted via Insert
Caption), inserting the new image and typing "Figure 2" underneath it
by hand would produce TWO images both labelled "Figure 2" — the new
one and the original second image, which still reads "Figure 2"
because plain text has no awareness that anything changed around it.
The original "Figure 3" would also stay "Figure 3" even though it's
now genuinely the fourth figure in the document — every caption from
that point on would be silently, permanently wrong until someone
manually renumbers each one by hand.

WHY THIS WORKS AS AN ANSWER
------------------------------
This is the concrete, hands-on version of this chapter's own claim:
a real caption field tracks its OWN POSITION relative to every other
caption sharing its label, recalculating the count fresh every time —
a manually typed number is just static text with no such awareness,
and inserting new content around it does nothing to update it.
