I'm a bit late, but it's useful to know that while dragging, keystrokes are handled normally. Using the parent comment's operation as an example, you can start dragging a folder in the Finder, then Command-Tab to the terminal (or hover over the Dock icon and then hover over the proxy window), Command-` to a particular terminal window, or Command-N to open a new one, and then type "cd " before finally dropping the file. ("cd " is nicely left-handed for those using the right hand for the pointing device.)
