To get the full signature of a method call using keyword completion, which key combination should you use?

The key combination Shift + Enter is used to retrieve the full signature of a method call in the ABAP development environment. When you're writing ABAP code and you want to quickly understand the parameters and return types of a method, pressing Shift + Enter will bring up a detailed view of the method signature, which is especially useful for developers who are working with unfamiliar methods or those that involve multiple parameters.

This capability enhances productivity by providing immediate feedback and reducing the need to look up documentation separately. It allows developers to write code more efficiently by easily accessing relevant information while remaining in the coding environment.

Other key combinations may serve different functions in the development environment but do not specifically provide the method signature in the same way. Understanding this key functionality can significantly improve your workflow when programming in ABAP.
