Not insert mode

The intention of not insert mode (or insert mode off) is to make it easy to move vertices and modify a currently existing graph without adding new vertices and edges. It is also possible to add vertices in this mode but it is much less intuitive than in the insert mode. To add vertices click with the right mouse button on an empty area and select Insert vertex.

To move vertices in this mode it is just to press the mouse button when the mouse pointer is in the middle of a vertex and drag the mouse with the mouse button down until the mouse pointer is at the position where you want to place it.

To get a menu with commands click with the second mouse button in the graph window. The commands are different depending on the selection of vertices and edges.

Merge vertices

It is possible to merge two vertices in the not insert mode so that the resulting vertex is neighbour to all vertices that the vertices in the merging are neighbours to. To merge two vertices press the mouse button in the center of a vertex and drag the mouse so that the mouse pointer is at the center of the vertex you want to merge it.
