Move through images in a folder with Preview.app When looking at an image in a directory with the Preview application, I'm used to the Windows behaviour of using the &#x2190;/&#x2192; 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?
If you are just skimming the pictures do this:

Instead of opening a picture in Preview.app by double-clicking it, just press space to preview the picture when selected in Finder.

This way you can still use the arrow keys to navigate between the pictures. 


&#x2191; and &#x2193; in list view
&#x2191;,&#x2193;,&#x2190; and &#x2192; in icon view


You can still open the picture in Preview.app when needed (top right corner).
