IntelliJ IDEA 2021.3 Help

Run tool window

The Run tool window displays output generated by your application. If you are running multiple applications, each one is displayed in a tab named after the run/debug configuration applied.

If you re-runan application, the new output overwrites the contents of the tab. To preserve the output of an application, even if you re-run it, pin the output tab.

Learn more from Debug a Vue.js application, Debug an Angular application, and Debug a React application.

The appearance of each tab depends on the type of the application being run and can include additional toolboxes and panes.

IntelliJ IDEA enables you to split the active Run tool window by invoking specific actions from the context menu. You can right-click the desired tab and select one of the split options: Split and Move Right or Split and Move Down. Another way to do this is by dragging and dropping the desired tab. IntelliJ IDEA highlights the available areas in the tool window where you can place the tab. To unsplit the tool window, right-click the top pane and select Unsplit from the context menu.

The main toolbar of the Run tool window lets you rerun, stop, pause, or terminate an application. The following table contains descriptions of the buttons that are common for most applications.
