Open external image editor quickly from within Xee (with keyboard shortcuts)

I would like to see 2 or 3 keyboard shortcuts added that would open the image 
in a user assignable editor.

For example, I would like one that would open the image in Preview App, and 
another that would open the image in Photoshop, and a third that would open the 
image in Acorn.

If they user assignable to which editor they open, then users can pick their 
own editor to link to.

And the reason I would like 3 is because I use each one of the editors above 
for different things, depending on what I need done, so this would allow 
quickly opening that external editor with the image I want to edit.

Thanks
