Edit, Cut, Copy, Paste, and Suggest on Your iPhone
Select a block of text to copy or cut.
Here’s how to exploit the copy-and-paste feature. Say you’re in the Notes app, jotting down ideas that you want to copy into an e-mail message. Double-tap a word to select it, and then drag the blue grab points or handles to select a larger block of text. (You can use the handles to contract selected text too.)
After you’ve selected the text, tap Copy. (If you want to delete the text block, tap Cut instead).
