The first one is the default value; in it, the system's proxy settings will be used if and only if the user has never set his org.gnome.system.proxy.mode key.  Once the user sets that key, use-system-settings will switch to "system_values", which indicates that the system's proxy settings should be used, or "user_values", which indicates that the user's settings should be used.  The key will alternate between these last two values in the future and will not go back to the default value.</description>
