Free program WinKey lets you assign Windows key shortcuts to your heart’s content.

Many of us don’t like our mouses: Not only can they cause repetitive strain injury, but they can slow us down. This program returns you to the "old school" of computer operation by helping you create keyboard shortcuts to access your favorite programs, documents, and files. Once you’ve made a shortcut, simply press your desired key combination to launch your program. This tool supports up to 200 key assignments, giving you lots of choices and room to grow.
