Adding new nodes
New nodes are added using the pen tool.
Press and drag from an existing node or arc label to connect to it a new node. The new node will appear at the point where you release the mouse button.
Click in free space to create a new node without any connection.
The style that is given to a new node depends on the type of information map and the style of the node to which it is initially attached. For some types of map including argument maps, a menu will pop up from which you can select the type of node that should be created.
Dragging from an arc label is called splitting a link. Click here to see an example. This is a good technique which helps to reduce the amount of 'clutter' in a map.
When the new node appears there are several things you can do:
With the pen tool, click on its text label to edit the label.
With the pen tool, hold down the Ctrl key and drag to change its location.
With the pen tool, drag from the node to another node to link the two nodes.
With the pen or arrow tool, right-click (or on a Mac, Command-click) to pop up a menu of options for setting the node's visual styles.
With the eraser tool, click on the node to delete it.
With the eraser tool, click on a link to delete the link.
