Enable arrow keys to switch to next/previous picture in slideshow-mode
I like the slideshow because it shows the pics fullscreen. Yet, I don't like to watch at the preset speed, because there may be some pictures that I'd like to view longer and some that I'd rather skip.
The current procedure with the navigation bar is cumbersome:
1) the bar quickly disappears
2) you have to move the mouse to make it pop up again and hit that smallish next button
3) photo is resized everytime the bar reappears
All of the above makes navigating the slideshow a hassle, whereas being able to browse the slideshow manually with the arrow keys would make it a breeze.
That is already available
