Using the Mouse

• Left-click on a node selects this single node.

• Left-click with the Shift button pressed extends the selection from the node last selected to where the mouse is now as one area.

• Left-click with the Ctrl button pressed inverts the node's selection.

• Left-click on the expander to open/close the subtree.

• Right-click on a node to open the context menu. The commands in it are executed with the left mouse button.

• Double-click on a diagram to open it.Double-click on a node with a subtree that isn't a diagram to open/close the subtree.

• Left-click, hold and drag to start drag-and-drop.

  If you get a node which was not previously selected, this is the only node to get the selection and all other nodes are deselected. If you select multiple nodes and drag one of them, they are all dragged.

  If you reach the top or bottom edge of the tree when you are dragging the nodes, your dragging is stopped for a second and the diagram is automatically scrolled to show more elements.

  If the mouse hovers over a collapsed node when dragging, the node is expanded and the contents is shown.

• The vertical scroll bar can be moved by pulling the scroll bar on the screen up and down or by using the mouse wheel; it does not matter what position the mouse is in.
