Using FreeMind mind-map software, how to space nodes?

From http://freemind.sourceforge.net/docs/features/0_8_0/Features%200.8.0.html

Approaching the inner side (i.e. the side that is closer to the root node) of a node you'll notice that the mouse cursor changes and that a small ellipsis appears. In this area you can simply drag and move the node pressing the (left) mouse button. Moreover, if you press the control key simultaneously, all nodes on the same level get a bigger or smaller spacing. In other words, the siblings of the moved nodes get more or less space in between.
