Override codes go in braces in the Text field and apply to the text after
them. Modern renderers treat an SSA script like an ASS script, so in practice every
tag on the ASS override tags
page works here too.
Codes in the specification
The original specification lists these. Its revision marks ASS additions in red, which the surviving plain-text copies have lost, so which were in SSA v4.00 itself cannot be confirmed code by code.
