Editing path segments works similarly in Adobe applications. You can edit a path segment at any time, but editing existing segments is slightly different from drawing them. Keep the following tips in mind when editing segments:
If an anchor point connects two segments, moving that anchor point always changes both segments.
When drawing with the Pen tool, press Ctrl (Windows) or Command (Mac OS) to temporarily activate the last used selection tool (Illustrator) or the Direct Selection tool (InDesign and Photoshop) so that you can adjust segments you’ve already drawn.
When you initially draw a smooth point with the Pen tool, dragging the direction point changes the length of the direction line on both sides of the point. However, when you edit an existing smooth point with the Direct Selection tool, you change the length of the direction line only on the side you’re dragging.
In Illustrator or InDesign, if you’re simply trying to make a rectangle wider or narrower, it’s easier to select it with the Selection tool and resize it using one of the handles on the sides of its bounding box.
Using the Direct Selection tool on a straight segment moves the segment. However, when used on a curved segment, reshaping is unconstrained. Use the Reshape Segment cursor to reshape with touch input on touch-based devices and touch workspace. You can use it with the Direct Selection tool.
Hold the Shift key while reshaping with the Direct Selection tool to constrain the handles in the perpendicular direction. This enables you to reshape curves into semi-circular shapes. This also ensures that the handles are of equal length.
You can also apply a transformation, such as scaling or rotating, to a segment or anchor point.
In Illustrator, if you extend a path that ends in a smooth point, the new segment will be straight.
Select the endpoints.
If the endpoints are coincident (on top of each other), drag a marquee through or around both endpoints to select them.
Click the Connect Selected End Points button in the Control panel.

In Illustrator, only corner joins are used to join open paths.
Illustrator provides the option to join two or more open paths. To join one or more open paths, use the Selection tool to select the open paths and click Object > Path > Join. You can also use the keyboard shortcut Ctrl+J (Windows) or Cmd+J (Mac).
When anchor points are not overlapping, Illustrator adds a line segment to bridge the paths to join. While joining more than two paths, Illustrator first looks for and joins the paths that have end points stationed closest to each other. This process is repeated until all paths are joined. If you select only one path to join, it is converted into a closed path.
In this process, you may lose complex aspects of your art styles.
The output path has the appearance of the topmost path in the selection.
The join option only results in a corner join regardless of whether you select anchor points to join or the entire path. However, for overlapping anchor points, if you want the option to select a smooth or corner join, then use Ctrl+Shift+Alt+J (Windows) or Cmd+Shift+Option+J (Mac OS).
In Photoshop, you can move only anchor points in this manner.
Hold down the Shift key in addition to the arrow key to move 10 pixels at a time.
In Illustrator and InDesign, you can change the distance of a nudge by changing the Keyboard Increment preference. When you change the default increment, holding down Shift nudges 10 times the specified distance.
Select the entire path.
Select the Reshape tool (located under the Scale tool ).
Position the cursor over the anchor point or path segment that you want to act as a focal point (that is, a point that pulls selected path segments), and click.
If you click a path segment, a highlighted anchor point with a square around it is added to the path.
Shift-click more anchor points or path segments to act as focal points. You can highlight an unlimited number of anchor points or path segments.
Drag the highlighted anchor points to adjust the path.
