You have to add it to the list by putting something like this in your code:
code:
function OnGetScriptCommands(){
var commands = '<ScriptCommands>';
commands+='<Command>';
commands+='<Name>pause</Name>';
commands+='<Description>'+langstrings[94]+'</Description>';
commands+='<Parameters/>';
commands+='</Command>';
commands+='</ScriptCommands>';
return commands;
}
