 In this article, we take the ideas seen in the above references
 a logical step further. 
-These techniques together make it possible to implement a 
-new focus+context user interface with two important features.
-First, all connected information is visible in fine detail 
---- you always see everything where you can go. 
-Second, all view changes are fluidly animated without discontinuities
-and local spatial structure is approximately maintained in transitions.
+Starting from three simple principles:
+
+- the user should always see [fragments of] all link targets
+  "you should see where you can go to"
+
+- the link transition should be fluidly animated, so that the 
+  visible link target comes to the focus
+  "you should see how you go there"
+
+- the link transition and resulting view should make it obvious to the user how
+  to go back, without a "back button" [implies bidirectional links] 
+  "once you get there, you should see how you can get back"
+
+we apply and develope a number of user interface techniques
 
 The interface requires less rigid structure of the view than
 earlier interfaces. 
+
 To be able to show all the connected information near the focus,
 only the relevant fragments of the linked documents can be shown.
 Therefore, we must be able to fluidly animate a fragment to
