In the Navigation Pane, click Grammar, and then click Grammar Sketch.
After you generate a grammar sketch, you can use its features and contents in any of these ways:
To navigate in the sketch, use the hyperlinks that appear in the Contents pane, in text and various tables' column headings.
You should review the Residue section often, for example, to learn about unclassified affixes. This could be particularly important if you are using a parser.
Use the Back in Sketch or Forward in Sketch buttons to move backwards or forward to previously-visited locations in the sketch.
Press the shortcut keys Ctrl+F to open a Find dialog box so search in a sketch.
The Back and Forward buttons on the Standard toolbar move you between previously visited Navigation Pane tool (view) or records (entries, list items, and so on).
