Evaluate expression
You can execute expressions or reassign values for variables while your script is stopped by a breakpoint. The Evaluate Expression functionality helps you to obtain additional details about the program state or test various scenarios at runtime.
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.
