Compare the results of evaluating the two forms below:
(let ((pos (goto-char (point-max))))
(insert "foobar")
(overlay-put
(make-overlay (+ pos 2) (+ pos 3))
'after-string (concat "1" (propertize "2" 'cursor t) "34")))
(let ((pos (goto-char (point-max))))
(insert "foobar")
(overlay-put
(make-overlay (+ pos 2) (+ pos 3))
'after-string (concat "12" (propertize "3" 'cursor t) "4")))
Both display "foo1234bar", with "1234" coming from the `after-string'
overlay.
When you type C-f on the second `o' in "foo", the cursor will be
displayed on `2' with the first form and on `3' with the second. More
generally, the cursor will be displayed on the character in "1234"
which you propertize with a non-nil `cursor' property.
What I meant in my suggestion is to move the property from one
character to another of the `after-string' when the user types C-f
with cursor on the overlay. E.g., if the cursor is on `2' and I type
C-f, modify the `after-string' from
(concat "1" (propertize "2" 'cursor t) "34")
to
(concat "12" (propertize "3" 'cursor t) "4")
Then it will appear as if the cursor moved inside the `after-string'.
