Changing the Behavior of Alignment Guides
You can place your own alignment guides on any slide to help you line up objects where you
want them.
To place alignment guides on a slide:
1 Choose View > Show Rulers to make the rulers appear at the top and left side of the slide
canvas.
2 To create a vertical alignment guide, place the pointer on the ruler on the left side of the
slide canvas and drag to the right. A yellow alignment guide appears. Drag it to wherever you
want on the slide canvas.
3 To create a horizontal alignment guide, place the pointer on the ruler at the top of the slide
canvas and drag downward. Drag the alignment guide that appears to where you want it on
the slide canvas.
Even if you place your own alignment guides on a slide canvas, they will not appear during
the slideshow presentation. They are only visible when editing the slide.
You can also place your own alignment guides on a master slide so that they are available on
any slide that is based on that master slide. To read about setting your own alignment guides
on master slides, see “Adding Alignment Guides” on page 90.
To remove alignment guides that you have placed on a slide:
m Drag the alignment guide off the edge of the slide canvas.
If alignment guides are getting in the way as you work, you can temporarily disable them.
To temporarily disable alignment guides:
m Hold down the Command key while dragging an object.
You can turn alignment guides and size and position tags on or off in Keynote Preferences.
You can also have alignment guides appear only when object edges are aligned, or only when
object centers are aligned.
