Navigation in Diashow

[mohataj]

I have my collection ordered by topics.
To get some impression, I love to use diashow and struggling through a topic by random.
After having found a matching picture, I'd like to step for- or backwards the according pictures by arrow-key or anything else, rather than having the next random picture on key/klick. Maybe opening the browser for showing the folder would be nice.

sincerely
