What the Text Indenter does
Add a chosen prefix or indentation level to selected lines of text.
Add a chosen prefix or indent level to every selected line in one pass.
Why the Text Indenter is useful
Applying consistent indentation manually is repetitive and can introduce uneven spacing.
Reformatting quoted text or code blocks by hand invites missed lines, especially when the block runs dozens of lines long.

How to use the Text Indenter

- 3

Key features
- Custom indentation
- Blank-line options
- Preserves original line endings
Benefits
- Makes code snippets, outlines, and quoted blocks easier to format.
- Only the selected lines change, so surrounding text keeps its original shape.
Real-life use cases
Markdown replies
Indent a block of example code so it nests correctly inside a markdown reply.
Parser formats
Prefix every line of a manifest with two spaces to satisfy a strict parser.
Tips for the best results
- Use spaces for portable indentation in code examples unless tabs are required.
- Decide whether blank lines get the prefix too; some formats treat an indented empty line differently.
Conclusion
Indentation errors are most visible in context, so view the block in its destination once before moving on.
