iPad's Hidden Keyboard Characters

There's more than meets the eye with the iPad's on-screen keyboard. Holding down certain keys provides additional character options. A long tap on the Comma key, for example, brings an apostrophe. Right next door, the Period key offers up a quote mark too. On the numeric keyboard, shown here, the Quote Mark key hides smart quotes and other symbols if you hold it down for a second. Oh, and if you didn't know, hitting the spacebar twice inserts a period.
