1.Tap and hold virtual keys Other virtual keys hold special powers, too. Press and hold on a vowel, for example, and a pop-over window containing accented versions of the selected character appears. Consonants like C, S and N also offer alternatives when you tap and hold on their virtual keys. Similarly, holding down punctuation marks can provide extra options. The hyphen offers an em dash and bullet. And the dollar sign hides symbols for numerous currencies. 2.Avoid application exits Sometimes you notice something youâ€™d like to check out more closely in an app â€“ at the same instant you press the Home button. Instead of letting the app close, then finding its icon and waiting while the app relaunches, you can tell your iPad to abort your now-unwanted Home button press. If you hold down the Home button longer â€“ by just a few seconds â€“ your iPad will abandon its plans to close the current app and will carry on as before. 3. Fill your dock Brand-new iPads feature just four apps in the Dock. Because of that, many iPad owners keep just four apps in the Dock and donâ€™t think to add any more. But you can, if you want to. It turns out that the Dock can actually hold six apps if youâ€™d like it to. All you need to do to keep your more frequently accessed apps in the Dock is move them there. To do so, simply press and hold on any app icon until the apps start to jiggle, and then drag the app youâ€™d like to move right into the Dock, where it will stay.
