When Pauker is started, a window appeares simliar to the one shown in 1.
With the "Add New Cards" button, new cards are added to the current lesson. Pressing this button will open a dialog similar to the one shown below:
The upper part of this dialog contains items for basic editing functions (such as cut, copy, paste, etc.) Below them is a text field where the "front side" of a card is inputted. Below that, there is another text field where the corresponding "back side" of a card is entered. If the checkbox "Repeat by Typing'' is selected, you have to type in the back side of the card letter by letter when repeating the card. Pressing "OK" will add the card to the current lesson batch in the unlearned pile. If you want to add several cards at once, you can select the checkbox "Keep Dialog Open".
