@ -1544,9 +1544,14 @@ A good use case for filtering is the [Go programming
language](https://golang.org). The indentation is pretty opiniated, it even
comes with a filter called `gofmt` for indenting Go source code properly. So
plugins for Go often provide helper commands called `:Fmt` that basically do
`%!gofmt`, so they indent all lines in the file.
`:%!gofmt`, so they indent all lines in the file.
Related help: `:h filter`
People often use `:r !prog` to put the output of prog below the current line,
which is fine for scripts, but when doing it on the fly, I find it easier to use
`!!ls` instead, which replaces the current line.
:h filter
:h :read!
