Windows Clippings is a useful little tool for capturing clippings for documentation/blog posting.
It goes in the system tray and when you double click on it the screen dims. You single click on the window you want to get a screenshot of and just that window brightens. A double-click then will send the screenshot to the clipboard, OneNote, or a Folder. It’s even smart enough to pick a good filename based on the Window’s Title.
It will also create transparency in all the appropriate places, which is very useful when you consider that even Windows Explorer uses irregular regions and curved edges.
