Displaying the How To window during reviews
The Reviewing panel in the Preferences dialog box lets you make sure that the How To
window displays the appropriate topics during the review cycle. The How To window is
closed except when a tracked PDF document is opened in an email-based or browser-
based review.
To display the How To window:
1. Choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS), and select
Reviewing.
2. Select Reset Automatic How To Pages, and then click OK.
