Change the logic for handling the up and down keys when a note is focused because the old logic would prematurely move the note focus to another note even if the user could move the caret further up or down within the same note.
Change the logic for handling the up and down keys when a note is
focused because the old logic would prematurely move the note focus to
another note even if the user could move the caret further up or down
within the same note.

The new logic is to check immediately after the user presses the up or
down button when a note has the focus if the caret has been moved. If
the caret has not been moved then the focus is moved to the next or
previous note.
