The Element data window can most conveniently be viewed by pressing F5 (Window : Layout : Warrior layout). Note that you can collapse/expand individual data groups, and save your arrangement in a custom window layout.
Figure: The Element data window for an item about immunity. In the presented example, the element is listed at position #44576 in the collection and its title is "immun: Are T cells involved in regulating the immune response?". Element titles are automatically generated from the first question text. Item's priority is 5%. Next repetition in 2047 (interval of 32 years). The item has been repeated 8 times and scored zero memory lapses.

- Difficulty - show the estimation of the element's difficulty
- Restore layout (Ctrl+F5) - restore the SuperMemo windows layout chosen as the default one
- Element window (Esc) - shift focus to the element window
- Format intervals - format intervals as years, months, days, etc. If the formatted interval no longer fits within the field, click the field to display its entire value in a dialog box. Alternatively, hover the mouse over the field and read its value from the yellow hints panel in the status bar (Window : Hints must be checked for it to work).
