SEKE:* V 
Snaps to the nearest vertex. A vertex can be an endpoint of a line or line segment, corner of a polygon, or endpoint of an arc or curve. 
LTE Snaps
In the LTE Workspace Snaps and SEKEs behave with slight differences to standard TurboCAD methods. In the LTE Workspace the Vertex snap is called Endpoint.
To use a SEKE you must hold down the ALT key. E.g. the Vertex snap becomes ALT+V while in the LTE Workspace.
