soundlists

In every application that has sounds for events there is a file with .soundlist as the extension. This file contains descriptions of sounds and their corresponding events. The file looks like this:
          [__section_info__]
          description=Panel
          description[ca]=Plaf
          description[es]=Panel
          description[et]=Paneel
          description[fr]=Panneau de GNOME
          description[gl]=Panel
          description[ko]=г
          description[no]=Panel
          description[pl]=Panel
          description[pt]=Painel
          description[wa]=Scriftr

          [open]
          file=panel/slide.wav
          description=Expand
          description[ca]=Expandir
          description[es]=Expandir
          description[et]=Ilmumine
          description[fr]=Expansion
          description[gl]=Expandir
          description[ko]=
          description[no]=Utvid
        
The format is very similar to the .desktop and .directory files. The descriptions are found in the control-center (gnomecc). The section: [__section_info__] tells us that the name of the program for which the sound events are used is next. The [open] section has the sound event for the [open] action on the panel (clicking the foot-menu), and the rest is just like the .desktop files.
