Cross-references and Strong's definitions are indicated by a word in the Bible text with a dotted underline. They can either be opened with a long-press or a quick tap, depending on your app settings. Here's how to change your settings:

1. Open your Life Bible
2. Tap More in the bottom navigation
3. Tap Settings
4. In the Bible section, toggle on 'Tap to open cross-references' to open them with a tap. Toggle this same setting off to open them with a long-press.
