I am creating a new feature (polygon) in QGIS 3.2.2 and would like to easily add the vertices as I delineate a boundary. Currently, I can do this one by one as the cursor snaps to the vertex of the features in the layer I am referencing. But there are many vertices and (ideally) I would like to quickly go over the vertices and if they are within snapping distance they are automatically added to the new feature.

Is this possible?
