WinHotKey allows you to assign "hot keys" that do various things. Actions that can be done with a hotkey are:
1.Launch a Program
2.Open a document
3.Open a folder
4.Automatically type something
5.Control other windows on the screen

When running, WinHotKey sits in the system tray. Double-clicking on the system tray icon will bring up the main window.

WinHotKey works on Windows versions up through and including Vista. While not a 64-bit program itself, it works fine on 64-bit editions.
