Basic operations

Person cards are moved by dragging (the lines follow, staying straight horizontally and vertically).

Drag on an empty area to select a range: the people you enclose can be moved, deleted or put in a household box together (Ctrl＋click also selects several).

Relationship lines can be adjusted by dragging too: couple lines move left and right, parent–child and sibling lines up and down. Double-click puts them back.

Clicking a person or a line brings up a menu at the top of the screen: edit or delete, or press the Delete key to delete.

画面移動（パン）はSpace＋dragまたはdrag with the mouse-wheel button、turn the wheel to zoom、double-click to add a person。

In the chat (💬 Quick build) you can use the buttons or type free sentences such as “enclose Yamada Taro and Yamada Hanako in a household box”.
