+
+In Vim, insert some text into a file, such as `date`.
+
+In insert mode, press `!!` to switch to command mode and see a `:.!` prompt.
+
+Enter a command, like `bash` to execute on the given text.
+
+The text is replaced with the result from the command - `Sat Jul 12 23:16:29 BST 2025`.
+
+This also works for other commands, such as typing `1+2+3` and running `:.!bc` will return 6.
