Is there such a thing? Select next, press r, c or i and then a key to select next image annotation.
(thoroughly enjoying using the product btw)
<Tab> or <Shift>+<Tab>.
See Viewer Keyboard Command Overview (https://www.photools.com/help/imatch/#viewer.htm?dl=h-46), near the end of that table.
Thank you. Pls forgive me for not finding it myself.
