Challenge 1: Applying and Modifying Heading 1 in Writer — Solution Walkthrough

Steps:
  1. Type three section titles, each followed by a short body
     paragraph.
  2. Press F11 to open the Styles panel, ensure the Paragraph Styles
     tab is selected.
  3. Click into each title in turn and double-click "Heading 1" in
     the panel to apply it. Repeat for all three.
  4. Press F5 to open the Navigator.
  5. Right-click "Heading 1" in the Styles panel > Modify > change
     the font colour > OK.

Expected result:

After step 4, the Navigator's "Headings" category lists all three
titles as an outline — double-clicking any entry jumps straight to
that section.

After step 5, ALL THREE titles change colour simultaneously, since
they all read their formatting from the same shared Heading 1
definition.

WHY THIS WORKS AS AN ANSWER
------------------------------
This is functionally identical to the same exercise in Word &
PowerPoint Chapter 2 — the only differences are which key opens the
relevant panel (F11 here vs. the Ribbon's own Styles gallery) and
which key opens the structural view (F5 here vs. View > Navigation
Pane). The underlying mechanism — a paragraph style shared by all
three titles, modified once and reflected everywhere it's used — is
completely unchanged between the two applications.
