If a Keynote curve endpoint keeps attaching to an image, use an open shape drawn with the Pen tool when you need freely placed points. Apple documents connector attachment and alignment guides separately; turning off guides is not a documented connector-release method.

This guide covers one Mac desktop task: placing the end of a curved annotation exactly where you want it over an image. The recommended approach follows Apple’s documented drawing and point-editing tools. It replaces the troublesome connector when necessary, rather than assuming an undocumented setting can change its behavior. Draw a shape in Keynote on Mac.

Why does the curve endpoint keep attaching to the image?

Keynote’s connection lines are designed to join objects and keep them joined when those objects move. Apple explicitly describes dragging a curved line’s endpoints until they snap to objects. If your endpoint keeps attaching while you position it over an image, that behavior is consistent with a connection line. Add lines and arrows in Keynote on Mac.

The documentation reviewed does not provide a control to disable connection-line attachment or a modifier key guaranteed to release an endpoint. That is a documentation boundary: it does not establish that every possible interaction is unavailable, but it means a dependable tutorial should use the documented alternative.

First decide what the endpoint should do after you finish editing. A curve that should follow an object has a different purpose from a curve that should end at an arbitrary detail within a picture. Use this decision aid before changing settings:

Desired result Suitable approach
Keep objects joined as they move Retain the connection line.
Change the gap between an attached line and its object Use the connection line’s endpoint offsets.
Place the curve’s endpoint at an arbitrary location over an image Draw an open custom shape and edit its points.
Reduce alignment assistance while positioning an object Adjust alignment guides.

The table is a practical synthesis of Apple’s separate instructions for connection lines, custom shapes, and alignment guides.

Draw an open curve with an independently movable endpoint

For a fixed annotation over an image, the supported alternative is an open custom shape. Here, “open” means the drawing does not add a closing segment between its last and first points. Apple documents both open drawings and subsequent editing of their points. Draw a shape in Keynote on Mac.

Keep the original curve until you have checked the replacement. For an illustrative task, imagine an image containing a gray rectangle and a blue circle. You want the curve to end inside the blue circle. The endpoint’s position within the picture is the requirement; maintaining an automatic connection to the image object is unnecessary.

  1. Open the presentation in Keynote on your Mac.
  2. Click the Shape button in the toolbar, then choose Draw with Pen.
  3. Click to create the first point.
  4. Move the pointer and add the next point. To create a curved segment, click and drag, then click again to finish that segment.
  5. Press Return or Esc to finish with an open drawing. Clicking the first point instead closes it.
  6. Select the drawing and choose Format > Shapes and Lines > Make Editable from the menu bar. Apple’s drawing instructions.

With the custom shape editable, drag its endpoint to the intended location. Apple lists dragging a point as the action for moving a point of an editable shape. This is the documented point-editing path used here; it is not a claimed conversion of the original connector. Keyboard shortcuts for Keynote on Mac.

Check both ends before removing the old curve. In the illustrative example, the replacement should terminate inside the blue circle and retain the intended starting position. Judge the replacement against those two locations, then refine its contour. This avoids spending time matching the bend before the endpoints are correct.

Refine the curve without moving the whole drawing

Point editing and object positioning solve different parts of this task. Enter Make Editable before adjusting an individual point. Apple also documents double-clicking the edge of a custom shape to make it editable. For a smooth point, reshape the curve by dragging the adjacent line; for a Bézier point, click the point and drag its control. Keynote’s editable-shape shortcuts.

If you need Bézier controls, Apple documents Keynote > Settings > General > Curves default to Bézier. This changes the default curve behavior; it is not an attachment setting. Apple explains that shapes using Bézier curves are adjusted through handles on the point. Add and edit a shape in Keynote on Mac.

Use the point symbols to understand the contour you are editing. Apple identifies a square outlined in red as a sharp point with straight adjoining lines, and a circle outlined in red as a curved point with curved adjoining lines. Click outside the shape when editing is complete. Apple’s shape-editing guide.

If clicking near the curve keeps selecting the image, open the toolbar’s View menu and choose Show Object List. Keynote must be in Slide Only or Navigator view. The object list provides a way to select overlapping objects; it also lets you change their stacking order by dragging an object above or below another entry. This addresses selection and visibility, rather than endpoint attachment. Move and edit objects using the object list in Keynote on Mac.

When should you change alignment guides or endpoint offsets?

Alignment guides help position objects relative to other objects or the slide. To change them, choose Keynote > Settings > Rulers, then deselect the relevant guide options, such as guides at object centers or edges. Use this when alignment assistance is the obstacle during object positioning. Use alignment guides in Keynote on Mac.

Apple also documents Command-drag to turn off alignment guides while moving an object. It does not describe that shortcut as disabling connector attachment. Its meaning depends on the action: the same shortcut list assigns Command-drag of a selection handle to rotation. Do not treat it as a universal endpoint-unsnap command. Keyboard shortcuts for Keynote on Mac.

If you want to retain a connection and only change its visible gap, select the line and adjust Offset Start and End in the Format sidebar’s Arrange > Connection section. Apple documents these values as spacing between endpoints and connected objects. They are not documented as arbitrary endpoint coordinates. Add lines and arrows in Keynote on Mac.

Does Apple Pages document the same drawing approach?

Yes. Pages on Mac also documents Shape > Draw with Pen, curved segments, and Format > Shapes and Lines > Make Editable. Its instructions specify Esc to leave the drawing open. This corroborates the custom-shape approach within Apple’s Mac apps, while the Keynote instructions above remain the relevant steps for a presentation. Draw a shape in Pages on Mac.

For the final check, confirm that the curve ends at the intended detail, that both endpoints remain where you placed them, and that the contour looks right with editing handles dismissed. Keep a connection line when its attachment serves the slide; use the open custom drawing when the task calls for independently positioned points.
