Hi guys. I'm trying to familiarize with Delphi as better as possible. And now I've started flicking through the Delphi Demos to get more info about Delphi's features and possibilities. But unfortunately some demos do not have any description or comments.
So now I can't figure out what the next demos demonstrate:

Demos\DelphiWin32\VCLWin32\VirtualListView
Demos\DelphiWin32\VCLWin32\ToolsAPI\ActionServices
Demos\DelphiWin32\VCLWin32\ToolsAPI\Editor KeyBinding
Demos\DelphiWin32\VCLWin32\ToolsAPI\INTAServices
Demos\DelphiWin32\VCLWin32\ToolsAPI\PackageDemo
Demos\DelphiWin32\VCLWin32\ToolsAPI\Productivity
Demos\DelphiWin32\VCLWin32\ToolsAPI\XPAppWiz

If somebody could give me a brief description about these demos, their functionality, components are used or shown in their code, it would be great for me.
I only have to know the sense of them. I'll be able to figure out with them deeper myself.

Thank you.
