Debug Tool Window. Frames
The Frames pane enables you to gain access to the list of threads of your application. 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.
