Select > All Points: This function will select all network elements on the topology map.
Select > Neighbors: Highlights all neighbors of the node that was right-clicked over.
Select > Nodes on Selected Links: Highlights the two endpoints of every selected link.
Select > Single-End Neighbors: When you right click on a node, there is an option to select single-end neighbors. Selecting this will highlight any peripheral nodes (single-ended nodes, attached to only one link) that are connected to the selected node. The selected node will remain highlighted. Typically, the selected node is a router, and the nodes that are subsequently highlighted are loopbacks and single-ended LANs.
Select > Tree: Available when you right-click on a node, this option will find the largest tree in the network that contains the selected node and highlight all nodes in that tree. A tree is defined as any group of nodes that are connected to each other in such a way that there exists only one available path between any two nodes in the group. (Note: in selecting the tree, this option will stop once it hits a node that belongs to a cycle.)
Cut Selection: This allows you to cut from the network all currently selected nodes and any links that (both) originate and terminate at the selected nodes. This action is reflected in the topology map. The cut elements are stored in the clipboard and can be pasted back into the network (multiple times if desired) at a location specified by you.
Copy Selection: Clicking this when one or more nodes are selected will copy to the clipboard the selected nodes and any links that (both) originate and terminate at the selected nodes.
Paste: This will paste the most recently cut or copied elements onto the topology map. Once pasted onto the map, the elements can be dragged around with the mouse and positioned at an appropriate location. Numerical characters are appended to the names of each pasted element in an ascending order to maintain an unique identity for each element. Any XML router-config data associated with the pasted nodes are carried over as well.
