You can't really trust that list regarding available stuff. You can get a list though by doing the following:
Use 'Run' and type in the following:
HTML Code:
Path:\To\Your\Graal\Client\Graal6.exe -listscriptfunctions
(your .exe file might have another name, you should fix that one then)
After that check your Graal folder. There should be a file called
scriptfunctions_client.txt. That list includes all (I believe) currently available functions
