Ctrl+Click to go to type definition, then click "Back"

Another possibility: hover mouse cursor over type. I'm not sure if there's such feature in Delphi, but in Lazarus if u have variable declaration like
Code:
var
  x: TVector;
then when user points mouse cursor over TVector, it displays hint which says in which file this type is declared like:
TVector = record
C:\Dev\MyLibrary\Geometry.pas
I believe that Delphi since 2007 does this too

If u use Notepad, than it it would be indeed more difficult to say which type u use in current unit. Perhaps I would then have to scroll file to top to observe used unit list. But when using IDE there should be no problem
