# Review text and layers

> Correct source text and translation without losing the page's editable structure.

Select a text layer on the canvas or in the inspector. Source analysis, semantic text, and visual layout are separate, so you can correct OCR without rebuilding the text box.

## Correct the text

A text layer holds source text, a translation, typography, writing direction, and either its own frame or an automatic fit to a detected region. Source text and translation are edited in the expanded layer row of the inspector.

Edit **source text** when OCR is wrong. Edit **translation** for meaning, tone, names, or line breaks.

<Note>
  Koharu renders translated text only. A source-only layer does not automatically show its OCR text
  on the canvas or in exports.
</Note>

## Manage layers

The layer view follows the page hierarchy: groups, text, raster layers, and image or artwork layers. The list selects one layer at a time; select several layers on the canvas with a modifier click or **Edit → Select All Layers**. Use the arrow buttons to reorder a layer among its siblings, toggle visibility, change opacity, and delete a layer with its descendants.

Analysis regions describe model findings. They are not visible presentation layers and do not compete with artwork or text during selection.

## Review a page

<Steps>
  <Step title="Check detection and OCR">
    Verify the text regions, then correct source recognition errors.
  </Step>

  <Step title="Review the translation">
    Check meaning, tone, terminology, and names against the source.
  </Step>

  <Step title="Inspect the artwork">
    Look for remnants of source lettering and damage around cleanup regions.
  </Step>

  <Step title="Check the reading experience">
    Adjust typography and fitting, then inspect the composite at normal reading size.
  </Step>
</Steps>

## Undo and redo

Use **Edit → Undo** or **Redo**. The defaults are `Ctrl+Z` and `Ctrl+Shift+Z` on Windows/Linux, or `Command+Z` and `Command+Shift+Z` on macOS.

Each page-stage result that the pipeline commits is its own undo step, so undoing a project run takes one step per page and stage. Closing and reopening a project loads the saved state without restoring the previous undo stack.
