RTFM will help you to "Read The... Flippin' Manual" entry for a highlighted language keyword/function by quickly directing your browser to lookup the term in your favourite documentation for that language. Unique settings for every syntax in Nova and fully customizable to target any (searchable) API-reference library. To get more details, RTFM!
Highlight a block of text and Translate in Place will translate it to any supported language you've chosen. TIP is powered by Google Translate and *your own* Google "Cloud Translation API" key. My understanding of their pricing (at the time this was written) is that it's free for the first 500,000-characters/month. See documentation for details and how-to. (Takes ~10 minutes to set up.)
