Hello all!
Just figured this out, so I thought I would share with you.
Mousetrap has in its sample configuration, the way to double-click to
"go up" in Explorer (by sending the keys for backspace)
Here is the entry for Mousetrap.ini to do the same in XnView.
Note that the RGB (where I have "149 149 149" must be set to whatever
your browser-view's background colour is.
I like this color (it is a dark grey) for mine.
You can set it first in XnView through the menu: tools/options then go
to the "Browser" section, then to "Thumbnails" and check the box which
reads "Background colour" and then choose your colour; just remember to
put your RGB in this mousetrap.ini entry.
VoilĂ !
; GO UP A FOLDER IN XNVIEW
; Go up the folder just by double clicking on an empty area in the
listview of the browser window
