Is there a way to change language of opened file?

[Xotchkass]

micro by default picks language from file extension but in case if file does not have extension (which is common in config files), it doesn't match actual language or when I'm using scratch buffer, I can't find an option/command to manually set language (or maybe I'm just blind).
