While editing scripts in the script editor you can get intellisense which will show you the available objects. For example, if you type Project.
you will see:

Another example, if you type:

This window is SAX Basic scripting language Help.
If intellisense is not working (this is the name completion while editing scripts) then you need to re-register sb6ent.ocx. In a command prompt change directories to your install directory and type "regsvr32 sb6ent.ocx".
