Next Moves the X marker to the next vertex.
Previous Moves the X marker to the previous vertex.
Go Deletes any segments and vertices between the two vertices you select,
replaces them with single straight line segments, and returns to Edit Vertex
mode. If you specify only one vertex by entering go without moving the X
marker, the segment following that vertex is straightened if it is an arc.
Exit Exits Straighten and returns to Edit Vertex mode.
Tangent
Attaches a tangent direction to the marked vertex for use later in curve fitting.
Width
Changes the starting and ending widths for the segment that immediately
follows the marked vertex.
You must regenerate the polyline to display the new width.
Exit
Exits Edit Vertex mode.
Fit
Creates an arc-fit polyline, a smooth curve consisting of arcs joining each pair
of vertices. The curve passes through all vertices of the polyline and uses any
tangent direction you specify.
