Just select some text and use :Redact
to redact it. Use :Redact!
to clear
the text.
You can also map an operator with <Plug>Redact
:
nmap <leader>r <Plug>Redact
vmap <leader>r <Plug>Redact
Use :RedactedW
to persist your changes, so your file will still look the
same if you close Vim and open it again.
I wrote Redacted because I often have to paraphrase something I wrote, but it's hard to do it when you're looking at the original words; it feels like there's no other way to say it. So I though, "it would be nice if I could read a sentence, hide it, and then try to come up with a new way to explain it without looking at the original text". So there you have it. You could also use it to make something like flash cards; you can cover the answers with Redacted and select them in visual mode when you want to see what's behind.
