In the decompiled view, have an option to select an identifier and go to where it is defined. For example, if you put the insertion point on a variable, it should go to the variable declaration. And if you put it on a method name then the correct class should be opened, decompiled, and the code view goes to the method. The shortcut key for this should be F12 to follow Visual Studio's lead.
