Hello, I post it to wishlist too, I write here just for say: it would be a very-very useful feature: zoom out with right mouse button (after selecting zoom tool). Now, inkscape use it for shift+left button (or +/-, but it is slow to get off hand from mouse), gimp use ctrl+left (or +/-, but it doesnot work with numeric keyboard). So, it is hard a little bit to find "zoom out" after working hours with gimp (for me). Thanks!
