Hi Brian, I think we still only need one caret. With key board
selection there is only one caret location, i.e. where new text will be
inserted. With a multi-touch device the system software could define
the selection and set the caret at one end or the other. (There might
be justifications for setting it on the left, e.g. if you touched first
on the right end.)<br>
<br>
The UI ergonomics might be hard, i.e. the ability to accurately
position the caret, but it seems possible. <br>
<br>
Ignoring that, the gesture might be a touch followed by a slide or a
touch followed by a second touch while the first touch is still
"pressed".<br>

This is an interesting question. Today we have the ability via
AccessibleText to indicate both a caret location, and also a selection
(start, end). When you have a range of text selected, one end of the
selection has a caret and therefore keyboard manipulation of the
selection (shift-arrow) grows/shrinks the selection by manipulating
only one end of the selection range.<br>
<br>
In a multi-touch environment, there is (presently) no keyboard
mechanism for doing that at the same time on either end; you simply use
your finger. So... I'm not sure that we need a second caret until we
have a keyboard-operable way of doing that sort of manipulation.<br>

<font face="sans-serif" size="2">At first glance, it seems obvious
that
an AccessibleText would only have one Caret. However I have
begun to question whether we will soon need an ability to represent at
least a second Caret. Multi-touch technologies are allowing
users to select with multiple fingers. For example, instead
of defining rectangles by a sequential first and a second corner
selection,
rectangles are defined by simultaneous corner indications of two
fingers.
The two finger motions of pinch and enlarge are becoming commonplace
in multi-touch interfaces. </font> <br>
<br>
<font face="sans-serif" size="2">Thus I wonder how long it will be
before
there is a requirement of text selection from simultaneous touching of
multiple points, thus creating a need for two or more caret references
in a linear string of text.</font> <br>
