Keyboard shortcut to edit images (not view)

[tbm]

I have tried searching for this so apologies if I've missed it. I use one program for viewing images (XnView MP) and another for editing images (GIMP).

Viewing works fine - if I double click an image it correctly opens in XnView but I'm trying to create a simple keyboard shortcut to open the image in GIMP for editing. If I right-click a jpg I have the context menu option to Edit (which correctly opens the image in GIMP) so I'm just trying to make a keyboard shortcut point to that (open the image editor) and am getting a bit confused!

Create a user defined command with a script: open <curitem>; and assign it a keyboard shortcut in the same window

That works perfectly, thank you!
