If you choose Edit parameters on the element pop-up menu, press Ctrl+Shift+P, or double click the empty area to the right of learning buttons at the bottom of the element window, a dialog box with editable element parameters will open.

This dialog provides the following fields:

• Element title - title of the element
• Element number - it is the physical position of the element in the collection
• Interval - the interval between the last repetition and the next repetition (in days)
• Next repetition - date of the next repetition
• A-factor - current A-factor associated with the element (A-factors determine element difficulty)
• Forgetting index - current forgetting index requested for the element
• Ordinal - current ordinal number assigned to the element
• Category - field that makes it possible to move the element to another contents category (if there are categories defined)
• Comment - field that displays the comment associated with the element
• History - button for displaying the window with the element's repetition history

You are most likely to use the element parameters dialog box in the following circumstances:

1. Changing element's ordinal (open the dialog and type in the new ordinal). You can also change individual ordinals by editing them in the element data window
2. Changing element's forgetting index (open the dialog, press Alt+F, and type in the new forgetting index). You can also change individual forgetting indices by editing them in the element data window
3. Moving the element to another contents category (open the dialog, choose another category in the Category field, and click OK)
4. Adding a comment (type it in the Comment field)
5. Viewing the history of repetitions for a given element (click History). You can also view the history of repetitions by double-clicking the element data window
