# Blue Read Tool – Character and Match Display

The Blue Read tool displays characters and their matches via the following methods:

- This is how the tool indicates the markings of found characters.

- Labeled Characters (Not Matched)

  This is how the tool indicates labeled characters that have not been matched. Labeled characters are displayed in the color green.

  - The character in the lower left corner of each found character can be modified by clicking on the character and then entering the desired character via your keyboard.
  - Supported characters can be any single UTF-8 character.
  - Characters can be selected individually by clicking on them. To select multiple characters, use the Ctrl key and click each desired character. Using the Shift + Ctrl and dragging across multiple characters will select all the characters dragged across.
  - Selected characters can be deleted by using the Delete key.

- Labeled Characters (Matched)

  This is how the tool indicates a matched model, with labeled and matched characters. A green bounding box is drawn around the characters, and an attached tag on the lower left side displays the model name and the matched string.

  - Matches can be selected by clicking on the attached tag and editing the matched string. The string that is entered will be validated against the expected model's character fielding and string length.
  - In addition, there is a context menu associated with the attached tag, which allows you delete the match or edit the models.

- Found Characters (Matched on an Unlabeled View)

  This is how the tool indicates an instance of features and a match on an unlabeled view.

  - In this instance, the context menu associated with the attached tag also includes an option to accept the match.

- Found Characters (Matched on a Labeled View)

  This is how the tool indicates labeled and found features/matches that are grouped together. The yellow tag below the model is displayed when the match is selected.

- Found Characters (Matched on a Labeled View with a Mismatch)

  This is how the tool indicates that a labeled and found match includes a mismatch in the features. In this scenario, the found character that does not match the labeled character will be displayed in orange. Similarly, found characters which are not covering any labeled characters will also be displayed in orange.

### Overlay Checkbox

The overlay graphics of labels and markings are shown back and forth or side by side whenever you press Alt + Left/Right or enable each checkbox (Labels and Markings) on Image File Information.
