TextBuddy: A Mac app for manipulating text

This looks really great and I'm definitely giving it a try.

I often find myself opening up TextEdit windows to do basic transformations manually.

A really common I case I have is changing indent levels. For example, adding 4 spaces to paste a code snippet somewhere that takes Markdown (but not code fences). This looks possible via the "Append Lines With..." command.

One thing I'm not immediately finding is a way to decrease indent levels.

For example, if I have an indented block of code like this:

    function blah() {
      if (foo) {
        baz
      }
    }

How do I decrease the indentation by 4 spaces, but preserve the interior indentation?
