My keyboard has special keys, like for sound muting or launching the web browser. With my stock Xfce 4.10 installation on Debian testing (Jessie) these keys are automatically mapped, so I didn't needed to configure them manually.However, I would like to change some of these bindings to custom commands. I might do so via the keyboard settings in Xfce, but I would rather change it the official way.Any ideas how to achieve this?
Where to find default bindings for special keys
debian;xorg;xfce
I think you're suppose to just use the standard dialog to do this, accessible under: Settings -> Keyboard -> Shortcuts.                       You can read all about this here in the Xfce official docs: Xfce Docs  Core  Settings Manager  Keyboard.
