1. 'Structure' panel: The 'Structure' panel shows you the content items in the document and their exact level within the document structure. In this case, the 'All Items' tab is chosen, meaning that every content item in the document is present in the structure view.
2. Connection between the 'Structure Panel' and the 'Document Preview': When you select a piece of content (e.g. the text segment: "It's time for an orange fizz"), the content will be highlighted and there will be a shadow path connecting the content in the 'Structure' window to the same piece of content in the document preview.

NOTE:
The 'Structure' panel will only contain the content of the selected content group/tab.

NOTE:
If you double-click on an item in the 'Structure' panel, the document preview will jump to the correct spread and then highlight that piece of content.

On the second page of our example document, we have two paragraphs that we want to segment into smaller units. As you can see in the document 'Structure', the whole paragraph is marked as only one text segment.

In order to devide this paragraph into smaller parts, we need to click on 'Tools > Apply Segmentation', which opens the 'Apply Segmentation' window.

1io Recipe Inc:
On the second page of our Recipe example, we have two paragraphs that consist of multiple sentences. Because our 'Translation Memory' (TM) contains translation units that are one sentence in length, we should also segment these paragraphs into single sentences. This increases the chances of finding exact matches in our TM.

For more details, please see the lessons on text segmentation.

NOTE:
The 'Text Segmentation Rules' used on a document should match those used for the 'Translation Memory'.

Within the 'Apply Segmentation' window you now have to choose the segmentation setting required:

1. Apply to: Here you can specify if you want to apply this text segmentation to the whole document, or just to selected parts of it.
2. Action: Here you can specify what kind of text segmentation action should be performed, e.g., segment the text according to segmentation rules, InDesign stories, paragraphs, etc.
3. Segmentation Rule: If you choose to segment the text according to segmentation rules, you can choose the appropriate rule set here.
4. Language: Here you can choose the language of your master document. The segmentation rule set should contain rules corresponding to this language.

When you have chosen the appropriate settings, click the 'Apply' button to perform the chosen segmentation on your choice of text.

1io Recipe Inc.:
For our segmentation purposes we are going to apply the segmentation to the whole document by the means of segmentation rules. The rule we will choose is the "one2edit Default" rule set. This will segment our paragraphs into single sentences. Furthermore, we choose our source language, English (US), because we know that our rule set contains rules for this language.

NOTE:
The one2edit Default segmentation rules are always available. These rules will segment English, German and Dutch languages into sentences with some degree of accuracy. However, they should NOT be considered a complete rule set and are only provided for reference purposes.

After applying your segmentation rules, the text content of the document should now conform to whatever segmentation is used for the entries of your 'Translation Memory'.

1io Recipe Inc.:
After applying the segmentation rules, our document's paragraphs have been segmented into single sentences, as we can now see in the 'Structure' window.

NOTE:
The underlying InDesign® document stories have NOT been affected by this segmentation. The segmentation is purely for ease of translation, and if an INDD file was to be exported at this point, the stories would be intact.
