Moving Vertices and Tangents

You can move vertices and tangents using the Move and Scale options of the Edit Mode box:

To move a vertex or tangent in any direction, select Move. Click the vertex or tangent and drag.
TipIf you have trouble selecting a tangent handle that is very close to the vertex, hold Q then select it.
To move selected vertices in any direction, select Move. Click one of the selected vertices and drag.
To move one or more selected vertices in the direction perpendicular to their tangents, select Scale. Click one of the selected vertices and drag.
To ensure better continuity on a garbage mask, automatically adjust tangents as you move vertices or scale the mask. Press and hold G and then drag a vertex. See Automatically Adjusting Tangent Handles of Adjacent Vertices.
