Explanation
Launchers are invisible areas that can be placed over any part of the application. They listen for an event, such as a click or a hover, and when that event occurs, they launch an OGL item, such as a Process Guide or a Message Guide. This provides context-sensitive help or guidance to the user based on where they are in the application and what screen element they interact with. For example, you can launch a Process Guide or a Message whenever a user creates a purchase requisition. This can be to inform the user of policy changes, approval limit changes, or compliance actions. References: Introduction & Overview of Oracle Guided Learning
