What were you doing:
Selecting some text which was larger than the visible screen
What feature did you use:
I selected a word by pressing it (as usual) then extended the selection by using the down arrow on my magic keyboard
As soon as the selection reached the bottom of the screen, nothing scrolled so I could not see what I was selecting. When I stopped pressing the down arrow, the screen immediately scrolled to the top of the selection.
What did you expect to happen:
I would expect the screen to scroll to show the current selection point
I was able to select by inserting the caret, scrolling to the end point of the selection and doing shift-click to select the text between those two points.
