IntelliJ IDEA 2018.2 Help

Debug Tool Window. Frames

The Frames pane enables you to gain access to the list of threads of your application. You can also export to a text file and customize thread presentation. To examine a thread, select it from the drop-down list on top of the pane. The status and type of a thread is indicated by a special icon and a textual note next to the thread's name. For each thread, you can view the stack frame, examine frames, navigate between frames, and automatically jump to a frame's source code in the editor.

To examine the values stored in a frame, use the Variables pane of the Debug tool window.
