Hi PhyrePhoX,
to answer you question:
Are you sure your left and right key are not used during record mode?[/color]
yes both keys are without any function in the recording mode (A720).
Hi Barney,
thank you for responding. It may not of interest of everyone, agreed. I personally like the one push key, because I use this function nearly on every second shoot. Often I forgot (or not fast enough) to push the key in the setting time of 2 s automatically review. As written, the playback "shift gears" seems not a reliable mechanic solution to use for thousands of images to review after shooting.
Additionally you brought another idea into the nice-to-have discussion: define functions to buttons (e.g. a dedicated script starts on button "right").
