My keyboard doesn't have media keys and I've always used Super shortcuts for media keys. However in Ubuntu 12.04 they no longer work.
I want:
- Super+C - Play/Pause
- Super+X - Stop
- Super+Z - Previous
- Super+V - Next
I've tried replacing "Super" with "Mod4" in gconf-editor in /apps/gnome_settings_daemon/keybindings after setting them in Settings → Keyboard → Shortcuts.
I've checked other keybinding locations but have found no other media keybinding settings in gconf-editor.
My muscle memory thanks you in advance ;)
