If you're using an OLE enabled application (such as Microsoft Word), you can create short-cuts that are bookmarks to Word documents (for example).
Start the application (Microsoft Word in this case) and load the document you're working on
Make a selection (highlight) and right click on it (don't let the right mouse button mouse go...)
Drag the mouse over to the desktop (or any other folder, etc.) and let it go
Select "Create document short-cut here"
Now every time you double click on the newly created short-cut, it will load Word, the document you were working on and take you to the place where you made the selection -- much like a bookmark.
