Flat Review 
But just what is this? 
Flat review is the ability to read completely, using the review  cursor a document or text content of a window.
 To better understand, we make a differentiation. 
The object navigation allows the User to access the 'objects one by one, so it is not possible, for example, go through two buttons in the same window without having to repeat the commands NVDA+4 or NVDA+6. I.I, object to object. 
The flat  review, on the other hand, allows you access all the content of the window or document at the same time, appearing as it is presented to the sighted. 
To exercise: 
» 
Go to "My Computer"; Locate your local disk c; 
» 
Press the applications or the right mouse button; 
» 
Find the option "Properties" and enter it. 
» 
Find tab in the window cleaning disk and open it. 
» 
Inside, press NVDA+7 to switch to flat review.
» 
After this, if you want to go to the top of the window, type shift +7. 
From there you can read the entire text of the window with the commands proofing and if you prefer, you can continuously read using the command numpad plus (). 
If you want to activate an object within that window as a button, for example, position the review cursor in the text area corresponding to it. (Okay or cancel for example). Press NVDA+numpad bar to place the mouse pointer over this object and then press Numpad bar once or twice for click or double click with the left mouse button respectively.
If you want to restrict the review to only one object of this window, press insert +1. 
To illustrate, Take the same window as the disk cleanup. 
When you turned the flat review, it was shown the entire content. (All items). If going to the top of that window, you press NVDA+1, the review will be restricted to the title bar, since this is the first object and the window is where you were initially. 
In windows application installation, you can also use it to review the dialogue with more calm, as the insert command + b only reads the continuous and may pass unnoticed some important information. 
You can also copy text from these windows using commands on the review cursor. 
Just being in a window, after having activated the flat review: 
» 
Walk with keys proofing until the beginning of where you want to copy; 
» 
Mark the beginning of the text to be copied wusing NVDA+f9; 
» 
Walking back to where you want to be the end of the text and press insert + f10. 
» 
You will hear the message: Review selection copied to the clipboard.
