 6. You can mark all untranslated texts as translated ones by `mark` command: `mark {index_or_name} -l {lang}`
 7. You can rename a name of translations by `rename` command: `rename {index_or_name} -l {lang} -t {new_lang}`, where `{new_lang}` is new one.
 8. To merge translations from another TranslationIndex into current TranslationIndex, use `merge` command: `merge {index_or_name} -l {lang} -s {source_index}`, where `{source_index}` is the source index to merge from. This enables you to use translations of old game to that of new game when new one is released.

+9. You can use `-a` option to enable [AI translation](#use-ai-translation) and [UlionTse/translators](#使用uliontse-translators翻译) translation to load translation settings from the config file automatically. It reduces some args to enter for these commands.

 5. [0.4.1] 打开RenPy游戏、保存文件的所在位置（仅限Windows平台）：新命令`open`可以打开与TranslationIndex关联的游戏可执行文件所在位置：`o {peoject}`。一些保存文件的命令（如`savehtml`、`saveexcel`、`dumpexcel`等）在保存文件后会自动打开文件所在位置，如果要阻止这种行为请在相应命令后面添加`-nw`选项。
 6. [0.4.1] [UlionTse/translators](#使用uliontse-translators翻译)翻译：`translate {index_or_name} -t ts -n bing -l {lang}`
 7. [0.4.2] 使用`new_file`创建来自单个文件的FileTranslationIndex：`nf {file_path} -s {type}`，其中`{type}`指定了生成该文件的工具类型，可选的值有`mt`（MTool生成的ManualTransFile.json文件）,`xu`（XUnity Auto Translator生成的_AutoGeneratedTranslations.txt）,`tp`（Translator++生成的xls/xlsx文件）。之后像往常一样使用其他命令进行操作FileTranslationIndex。FileTranslationIndex不支持以下命令：`inject`,`count`。您可以使用`nf -l`和`nf -h`查看详细说明。
