Run Anything?

Everyone knows that you can click Start, Run and run a program by typing in its name. However, many Windows users don't know that you can run a program by dragging its icon to the Run dialog box.
If you click Start, Run, you can drag a program's icon to Run's Open entry box and press Enter to run that program. You can also drag a registered document file to the Run dialog box to open that file in its associated program.
