The shortcut bar appears on iPad above the keyboard when predictive text is turned on. You can show or hide the shortcut bar.
Buttons on the shortcut bar in Numbers let you cut, copy, paste, and duplicate text. You can also add bold, italic, and an underline to text.
If you don’t see the shortcut bar, swipe up on the white handle above the center of the keyboard. If you still don’t see it, predictive text may be turned off for the keyboard.
