You can join two objects with a curved, straight or right-angle connection line. If you move one or more connected objects, they remain joined by the line. This is especially useful if you’re creating a flowchart.
Before you do this task, add two or more objects to the slide that you want to connect.
Go to the Keynote app
on your Mac.
Open a presentation with two objects, then click
in the toolbar.
From the Basic category, click the curved line to add it to the slide (you can change it to a straight or right-angle line later).
Drag one endpoint of the line until it snaps to an object, then drag the other endpoint until the line snaps to another object.
Do any of the following:
Change the curved line to a straight or right-angle line: Click the line to select it, open the Format
sidebar, click the Arrange tab, then click Straight or Corner.
Change the amount of space between the endpoints of the line and the objects: Click the line to select it, then adjust the Offset Start and End values in the Connection section of the sidebar.
You can change the look of the connection line by changing its thickness, colour, line style and endpoints, and by adding effects like a shadow and reflection.
