Direct Selection tool modifier keys in Blend for Visual Studio
The following table lists shortcuts that you can use to modify the shape of an existing path with the Direct Selection tool 
. To add or remove points on an existing path, or to join two existing paths, use the Pen tool.
| To do this action | Do this | Pointer |
|---|---|---|
| Make tangent handles appear for a point on a path | Click a point on a path |  Move point pointer |
| Move a point on a path | Drag a point on a path | Move point pointer |
| Make tangent handles appear for a segment between two points on a path | Click a segment of a path |  Move segment pointer |
| Move a segment between two points on a path | Drag a segment of a path | Move segment pointer |
| Change the angle of a tangent for a point on a path | Click a point or a segment of a path to make the tangent handles appear, and then drag one of the tangent end points |  Move tangent pointer |
| Make a point into a sharp corner or reduce the tangent to zero | Hover over a point, hold down Alt, and then click the point |  Convert point pointer |
| Make any sharp corner smooth (or, if it's already smooth, change the angle of the curve as it passes through the clicked point) | Hover over a point, hold down Alt, and then drag the point | Convert point pointer |
| Change a curve segment into a straight line | Hover over a segment in a path, hold down Alt, and then click the segment |  Convert segment pointer |
| Take a segment and bend it into a curve to pass through the pointer position | Hover over a segment in a path, hold down Alt, and then drag the segment | Convert segment pointer |
| Adjust one end of a tangent independently of the other side | Direct-select a point or a segment, hold down Alt, and then drag a tangent end point |  Convert tangent pointer |
