Add lines and arrows in Keynote on Mac
You can create a straight or curved line, then customize its look by changing its width (thickness) or color, or by adding different endpoints—for example, an arrow, circle, or square. Connect two objects with a line so they remain connected, even when they move.
Add and edit a line
Do one of the following:
Click in the toolbar, then in the Basic category, click a line. Options include a straight line with or without endpoints, or a line with editing points to create a curved line.
Click to select an existing line on a slide.
To move the line, click anywhere on the line, then drag it to where you want it.
To change the line length or rotation, drag the white squares on the ends of the line.
For a curved line, drag the green dot to change the arc.
To see controls for changing the look of the line, in the Format sidebar, click the Style tab.
Click a line style at the top of the sidebar, or use the controls in the Stroke section to adjust any of the following:
Line type: Click the pop-up menu above Endpoints and choose an option.
Color: Click the color well to choose a color designed to go with the theme, or click the color wheel to open the Colors window. (See Fill shapes and text boxes with color or an image in Keynote on Mac for more information on choosing colors.)
Thickness: In the field to the right of the color controls, click the arrows.
Endpoints: Click the Endpoints pop-up menus, then choose options to change the left endpoint and right endpoint.
If you can’t delete a line on a slide, it may have been added as a rule between lines of text. To learn how to remove it, see Add rules (lines) to separate text in Keynote on Mac.￼￼￼￼￼
Edit line curves and corners
You can edit a curved line to add right-angle corners or curves. As you edit, you can quickly change corners to curves and vice versa.
Click the line to select it, then, in the Format sidebar, click the Arrange tab.
Click the Curve or Corner button in the Connection section of the sidebar.
If you don’t see the buttons, make sure you selected a line with an editing point between the endpoints.
To change the position of the angles or the curve, drag the green dot.
Connect two objects with a line
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.
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, color, line style, and endpoints, and by adding effects like a shadow and reflection.
Tip: You can add a Connect button to the toolbar for quickly adding a connection line to selected objects.
To work with multiple lines at the same time, hold down the Shift key while you click the lines.
If you make changes to the appearance of a line, you can save it as a custom object style.
