Add a shadow to text in Keynote for iCloud
You can add a shadow behind text to make it stand out. The text shadow is visible even if you choose to print your presentation or download it as a PDF.
Select the text you want to change.
In the Format sidebar, click the Style button near the top.
If the text is in a table cell, click the Cell tab at the top of the sidebar instead of the Style button.
In the Font section, click the Action pop-up menu , then select the Shadow checkbox.
Adjust the shadow’s appearance using the following controls:
Blur: Click the arrows to increase or decrease the sharpness of the shadow.
Offset: Click the arrows to change the amount of space between the text and the shadow.
Opacity: Make the shadow more or less transparent.
Angle: Drag the Angle wheel to change the direction of the light source. You can also enter a value in the field next to the wheel.
Color: To the right of the text box, click the color well (it looks like a rectangle), then choose a color.
To remove a shadow, select the text, click the Action pop-up menu , then deselect the Shadow checkbox.
