Notes

While active the several actions and behaviors can be controlled by keys and mouse clicks.

The a key selects or deselects all.

Clicking a vertex selects it. While selected, holding down the left mouse button and moving the the cursor will move the vertex.

Clicking on a segment selects the segment (this is the straight guide line between two vertexes).

The hitting i key will add a vertex in this segment. The new vertex is now selected.

The t key sets or un-sets tangent (relative to view direction).

The p key aligns selected objects.

The s key can be used to snap a vertex to another vertex. With a vertex of the b-spline being edited selected, hold the control key down and left click the target vertex (as you would to control click multi-select). The hit the s key; the vertex is snapped together.

To unsnap vertexes, select the snapped vertex pair and hit the s key. The vertex of the b-spline being edited remains selected and can now be moved with the mouse.

The l key set or un-sets the linear interpolation.

The x, y, or z keys can be used to constrain the movement of the vertex while being dragged.

The q key exits edit mode.

Recompute is disabled during edit mode.
