ADOBE ROBOHELP CLASSIC: Modifying the Indigo Layout Copyright Notice
Sometimes a feature that seems like it would be simple to find is buried deep with an application's interface and becomes a challenge to locate. Such was the case when it came to changing the copyright notice in a responsive output.
In the image below, you can see that the default copyright year is 2017.
I searched every area of the layout for an option that controlled the default copyright information but could not find it. The reason? The option is not part of the layout. Instead, it's a project setting. To change the copyright information, follow these steps:
Choose Project > Project Settings
From the General tab, click the Advanced button
Click the Labels tab
Scroll down the long list to the Responsive Help section
Locate Copyright= followed by the copyright info
Click on the copyright info and then click the Edit button
