<h2 id="formatting_text">Formatting text</h2>

<h4 id="capitalization">Capitalization</h4>

<ul>
  <li>Use sentence-style capitalization for all UI strings: Words to live by.</li>
  <li>Capitalize all important words in:
    <ul>
      <li>App names (Calendar, Google Drive)</li>
      <li>Named features (Android Beam, Face Unlock)</li>
      <li>Proper nouns (Statue of Liberty, San Francisco Giants)</li>
    </ul>
  </li>
  <li>Be conservative. Don't capitalize words that aren't part of a formal feature name:
    <ul>
      <li>Sim card lock, Home screen, not Sim Card Lock, Home Screen.</li>
    </ul>
  </li>
</ul>


<h4 id="punctuation">Punctuation</h4>
<ul>
  <li><strong>Period.</strong> Don't use a period after a single sentence or
  phrase used in isolation, such as in a toast, label, or notification. Wherever two or
  more sentences run together, use a period for each sentence. </li>
  <li><strong>Ellipsis.</strong> Use the ellipsis character () (Option-; on MacOS and &amp;hellip;
    in HTML) to indicate
    <ul>
      <li>Incompleteness, such as an action in progress (Downloading...) or truncated text.</li>
      <li>That a menu item (such as Print or Share) leads to further UI involving significant
        choices. Exception: Commands whose wording already implies further (but limited) UI, such
        as <strong>Find in page</strong> or <strong>Pick a date</strong>, do not require an
        ellipsis. </li>
    </ul>
  </li>
</ul>
