Navigation Mode

The Navigation Mode provides convenient navigation means for a graph
and prevents its modification. yEd also provides an Edit Mode.
Either of these modes can be activated from the tool bar and the menu bar.
When yEd starts up, it is in Edit Mode by default.


Moving the viewport (Panning)
The current viewport (the visible diagram area) of the editor window can be changed
by dragging with the mouse. There are two different ways of moving the viewport. One is
activated by left-dragging and the other one is activated by right-dragging.
