You can copy or delete text or an object from one slide and place it on another slide.
Select the object or slide and choose Edit > Copy, or press Command-C.
Copying an object retains it temporarily in a holding area called the Clipboard so you can paste it to a new location.
Copy or cut the object or slide, and then do one of the following:
To paste an object, click the slide on which you want to paste the object. The object will be pasted into the same location on the new slide where it was on the original slide.
To paste an entire slide, select the slide (in the slide navigator) after which you want to paste the new one.
Choose Edit > Paste or press Command-V.
If you’re pasting text, its formatting is retained when you paste it. If you want the text to take on the formatting of the text in the location where you’re pasting it, choose Edit > “Paste and Match Style.”
Select it and choose Edit > Cut, or press Command-X.
Cutting an object retains it in a holding area called the Clipboard so you can paste it to a new location.
Select it and choose Edit > Delete, or press the Delete key.
Removing an object from a slide in this way does not retain it in the Clipboard.
Choose Edit > Copy or Edit > Cut, select the slide after which you want the new slide to appear, and then choose Edit > Paste.
Objects that have been copied or cut remain on the Clipboard only until you choose Copy or Cut again, or until you turn off your computer. The Clipboard holds the contents of only one copy or cut operation at a time.
