file). To access the command:
41+
- From the main menu: "Navigate" > "Jump to Last Opened Test" or "Jump to Last Opened Test Subject".
42+
- From the contextual menu: "Go To" > "Jump to Last Opened Test" or "Jump to Last Opened Test Subject".
43+
- From the "Find Action..." pop-up window: "Jump to Last Opened Test / Test Subject".
