There are some gestures you can use to help while entering text using the virtual keyboard. There are 5 that I know of. All of them involve tapping any key on the keyboard then dragging in a certain direction. In only one gesture does it matter where you tap.
- Enter: Tap Down
- Space: Tap Right
- Backspace: Tap Left
- Shifted Character: Tap on a character then drag Up. The shifted version of that character is written.
- Wiggle Delete: Tap and move left and right. Each movement deletes a character backwards, as though pressing backspace repeatedly. A fast way to delete a lot of text. (Of course, you must go left first, then right, left, right, ...)
