@LangKey for @Comment

[Akxe 0]

I have looked on unrelased documentation of @config (https://github.com/MinecraftForge/Documentation/pull/130) and found @LangKey as way to translate name to client's language, but I haven't found a way to do this for theirs comments.

 

@LangKey("config.modid.common.enabled.name")
@Comment("config.modid.common.enabled.decs")
public static boolean enabled = true;

 

This will produce correct name, but won't translate the @Comment.

You mean the tooltip? Because there's no way to translate comments...

Then 

config.modid.common.enabled.name.tooltip

will work. Just put the appropriate tooltip for the key in the lang file.
