You can't do it in place. I've obtained this by use of workarounds which you can see working pretty well in demo-caret-to-offset-patch.r and test-caret-to-offset-patch.r See my lengthy investigations in these files. http://anton.wildit.net.au/rebol/doc/field-text-draw.r http://anton.wildit.net.au/rebol/view/draw/smooth-font-scaling.r http://anton.wildit.net.au/rebol/patch/demo-caret-to-offset-patch.r http://anton.wildit.net.au/rebol/patch/test-caret-to-offset-patch.r Especially those last two files.
