Evaluate expression

When debugging, you can evaluate expressions to analyze the flow or prototype improvements.

If the expression is present in the code, hold Alt (on Windows and Linux) or ⌥ (on macOS) and click it. If you want to evaluate a specific code fragment, select it before clicking.

To evaluate an arbitrary expression, select Run | Debugging Actions | Evaluate Expression. A separate dialog opens that supports various constructs including loops, assignments, lambdas, and so on.
