Appendix A: Style override codes

This is a reference which may be useful for those of you who wish to learn the style override codes, so you can type them in manually without using the "override style" dialogue box.

All Override codes appear within braces { } except the newline \n and \N codes.
All override codes are always preceded by a backslash \
Several overrides can be used within one set of braces.

Each override affects all text following the override. To apply an override only to selected text, you need a second "cancelling" override after the selected text, to "undo" the effect of the first override.

Some overrides automatically apply to ALL the text - currently this is just alignment overrides, but more may be added later (eg. Shadow/outline depth overrides).
