I'm having a rather annoying issue with Evince. When I push F9 (it's the key i have hooked into songbird to change songs) it is the same as pushing page down in Evince. I've been through all of the controls, and Evince in theory should be turning the side pane on and off (however it only does this when i use super+F9). Any theories on how to disable this in Evince? I'd rather not change the key to change songs, I've got it across a few systems and I like it.

Thanks in advance for any help!
