Document Overview Methods
Document overview methods enable you to explore a document’s contents or layout. 
Browsing, for instance, lets you hear key sentences, so you can quickly skim a document. 
Summarization creates an overview of the main ideas in a document. This makes summarization an ideal study tool. For more information on using this feature as a study tool, go to Chapter 7, Annotations, Outlines, and Other Study Tools.
Layout exploration helps you determine what regions are on a page. For instance, it can tell you that there is a column on the left, an image at the top of the page, and a header half-way down the page.
Browsing in a Document
Browsing in a document lets you hear the first, last or both sentence(s) in every paragraph. By default, Kurzweil 1000 browses by the first sentence. To change this setting, use the Reading Settings page. For more information on settings, go to Chapter 12, Working with Settings.
To start and stop browsing:
Do one of the following:
•	Open the Read menu, and choose Start Browsing.
•	Press ALT+R, then W.
•	Or use the browsing shortcut, SHIFT+F5.
To stop browsing, you can also use the F5 key.
Summarizing a Document
You can use the Summarize tool to create a new document that contains a summary of the original document. For the summary document, Kurzweil 1000 automatically appends the word "summary" to the end of the original document’s name. You can save the file with another name by using the Save As command as described in Chapter 13, Files and Folders.
If you have bookmarks in the original document, you can use them to create the summary document. In addition, you can opt to include the page number of each bookmark. By doing this, the resulting summary document can become a useful study tool or table of contents. For more information on using Summarize and Bookmarks as study tools, go to Chapter 7, Annotations, Outlines and Other Study Tools. For more on Bookmarks, go to Chapter 5, Document Navigation Tools and Methods.
To summarize a document containing no bookmarks:
1.	Open the File menu and choose Summarize, or press ALT+F+M. 
A dialog opens and Kurzweil 1000 asks you to type the subject. 
2.	Type the subject, then press ENTER, or just press ENTER to let the system summarize automatically.
To summarize a document containing Bookmarks:
1.	Open the File menu and choose Summarize, or press ALT+, then M. 
Kurzweil 1000 asks if you would like to use the Bookmarks. 
2.	Press letter N for No or Y for Yes.
3.	Type the subject, then press ENTER, or just press ENTER to let the system summarize automatically.
Exploring Document Layout 
Kurzweil 1000 enables you to retain information about the layout, that is, the location and size of each word and rectangular section, known as "region." A region can be a any type of text block, such as table, header, footer, caption, title, etc., or image on a scanned page.
You can use the Explore Layout feature to find out how your page is segmented into regions, and potentially to reorder those regions. 
You can also use the Extract command in the Explore Layout dialog to extract an image into a TIFF file.
To explore layout:
1.	Be sure the Keep Layout Information setting is enabled in the General Settings tab. Go to Chapter 12, Working with Settings, for details.
2.	With a file open on the page that contains page layout, choose Explore Layout from the Tools menu, or press ALT+O, then L.
The Explore Layout dialog opens containing a read-only text box, a grid, and six command buttons. The text box and grid have no mnemonics but the commands do. They are UP (ALT+U), DOWN (ALT+D), Select (ALT+S), Extract (ALT+E), OK (ALT+O), and Cancel (ALT+C). If your cursor is in the text box or the grid, you can press the ENTER key for OK or the ESCAPE key to cancel.
The text box contains a brief summary of the page, indicating how many text and image regions it contains. Press the TAB key to get past that to the grid control.
A grid control shows a table of data. Like all tables, the data is contained in cells, and the cells are organized both by rows and by columns. You move from one line to another with the UP/DOWN ARROW keys. You move from one column to another with the LEFT/RIGHT ARROW keys. The HOME key takes you to the left-most column in the current row, END takes you to the right-most column in the current row. CONTROL+HOME takes you to the first cell in the table, while CONTROL+END takes you to the last cell in the table. F7 reads the contents of the current cell. SHIFT+F7 tells you the contents of the first cell in the current row (presuming you aren't in that cell), then tells you the contents of the current cell.
Each row describes a region. All of the text regions are shown in reading order. They are followed by pictures. The columns, from left to right, contain the region type and number, the number of lines in the region, what region or picture is immediately above the current region, what region or picture is immediately to the left of the current region, the first several words in the region, and then the top, bottom, left, and right edges of the region. Those edges are described in hundredths of an inch, or in centimeters, depending upon the value of the unit of measure setting. It should be noted that the number expresses the distance from the top edge of the image (for top and bottom), or from the left edge of the image (for left and right). If the top left edge of the page (after rotation), is not against a scanner corner, those measurements won't help you figure out the absolute position of the region on the page. Otherwise, they will.
You can move around the grid with the arrow keys, as described above. The current region, from the perspective of the command buttons, is the one described by the currently selected row in the grid.
The UP command swaps the contents of the current row in the grid with the row above it. The DOWN command swaps the contents of the current row in the grid with the row below it. When you get out of the dialog box with either Select or OK, the changes in the grid order are used to move text around in the current page, so that the reading order of the text reflects the order you have established in the grid. While the current control is the grid, you can use CONTROL+D to move the current row down, and CONTROL+U to move the current row up.
The OK command closes the dialog box, and positions your cursor at the beginning of the currently selected region.
The Select command closes the dialog and selects all of the text in the current region. This is particularly handy for deleting a region.
The Extract command extracts an image or picture region into a separate TIFF file. If your cursor is in the grid in the Explore Layout dialog, you can use CONTROL+E to activate this command, otherwise, you can use ALT+E from elsewhere in the dialog.
Layout information is useful in other ways. You can navigate from one region to another in a document by using SHIFT+F8, which advances the cursor to the beginning of the next text region, or SHIFT+F6, which takes the cursor to the beginning of the previous text region. CONTROL+F1 reports the position of the current word.
Document Overview Shortcut Keys
SHIFT+F5 starts browsing.
The following shortcuts are for Layout Exploration. They are also applicable to table formats elsewhere in Kurzweil 1000.
UP or DOWN ARROW moves the cursor one line up or one line down in the current cell or in the cell above or below, respectively. 
LEFT or RIGHT ARROW moves the cursor from one column to another. 
HOME moves the cursor to the left-most column in the current row.
END moves the cursor to the right-most column in the current row. 
CONTROL+HOME moves the cursor to the first cell in the table. 
CONTROL+END moves the cursor to the last cell in the table. 
F7 reads the contents of the current cell. 
SHIFT+F7 tells you the contents of the first cell in the current row from anywhere else in the row.
