+Peek Definition (Alt + F12) command (Visual Studio 2015+ only)
+----------------
+
+This feature can also be activated through Peek Definition context menu. 
+It opens a symbol definition in a special view, embedded into current one.

+was introduced only in Visual Studio 2015, so we cannot support it in previous 
+versions.
+
+Here is a screencast in VS2015:
