I have seen some really fast typing done by all thumbs but the iOS keyboard doesn’t quite facilitate that for most people. However, you can split the keyboard into two halves and move it around on your iPad screen. Simply press and hold the keyboard icon on the lower right side of the keyboard and choose“Split” and it will separate into two halves. You can stick it back together by pinching it together or by pressing and holding the keyboard icon. Your other choice is to“Undock” or“Dock”which means you can move the keyboard anywhere on the screen or move it back. You can also use your thumbs to "pull" the keyboard apart.
