Tapping and Holding Buttons and Icons on Your iPhone 4S

Part of the iPhone 4S All-in-One For Dummies Cheat Sheet

On your iPhone 4S, if you want to open an app, fill in a text field, or choose a command such as Print or Message, you tap the appropriate icon, field, or button. The tap and hold gesture opens another world of commands on your iPhone:

Text or image: Tap and hold any text or image to see the Select/Select All/Cut/Copy/Paste bar. Tap one of those tabs to perform that function.
123 key: Tap this key, slide your finger to the punctuation you want, and then let go. The punctuation is inserted in your text and the keyboard returns to letters.
Any icon on the Home screen: Tap and hold these icons until they begin to wiggle and jiggle. Then tap the X in the corner to delete the app from your iPhone or tap and drag them to a new position.
Any app icon in the multitasking bar (which you open by pressing the Home key twice quickly): Tap and hold one of these icons until you see an X in the corner. Then tap the X to completely close the app. This is very useful if your iPhone starts acting up and you remember you have a streaming app such as a radio program running.
