Compare selections of code within the same or different files

[Menchar]

I frequently want a quick way to compare selections of code within the same file, or a different file, from within VS. Comparing two files is the normal way of using CC, but how do I compare two different pieces of code within the same file, without exporting the pieces into separate files
