When looking at an image in a directory with the Preview application, I'm used to the Windows behaviour of using the ←/→ keys to move through all the other viewable images in that directory.
Preview.app doesn't do this - I first have to select all the images and then open Preview.app. This is a little annoying.
Is there something I can turn on or install to get this behaviour?
Also, how do I open an image in a new instance of Preview.app, say for comparison purposes?
