Editing text - think of the circle as an overhead view of a joystick
"it's simply impossible to pull the caret into the position desired to carry out an edit if that position is at the edge of the screen. Here I was trying to edit the word 'Create', and place the cursor at the start of the sentence. I found this was impossible."
Here's the solution I found to edit text - think of the circle as an overhead view of an old-school Atari joystick.
If you tap on the left side of the circle, the cursor will move exactly one space to the left. If you tap on the top of the circle, the cursor will move up exactly one row, etc.
