The relevant section of the Gnome HIG v2.0 reads as follows: Ctrl-scrollwheel-up should zoom into the window or control under the mouse pointer, and Ctrl-scrollwheel-down should zoom out. Zooming in this way should not move keyboard focus to the window or control being zoomed. A link to the relevant page in the gnome hig is here: http://developer.gnome.org/projects/gup/hig/2.0/input.html#input-mouse The bug in gnome bugzilla that led to this bug being filed can be found here: http://bugzilla.gnome.org/show_bug.cgi?id=309236 Reproducible: Always Steps to Reproduce: 1. Hold control and scroll the mouse wheel over firefox 2. Hold control and scroll the mouse wheel over a gnome program (evince, eog, etc.) 3. Notice the difference

Probably a dupe of bug 262715 or bug 141476 however given the hig data leaving open for someone to reconsider.

I think this is a valid integration issue -> confirming

The scroll direction will be changed in bug 141476 for all platforms.
