How to create a new keyboard shortcut using the Windows key?
AutoHotKey was built for this, as well!
#x::Run explorer.exe
would run explorer on winkey (#) and x (x). It's really that simple.
WinKey starts your favorite applications, folders, and Web pages instantly.
This shell extension allows you to define keyboard shortcuts with the Windows key. You can use almost any key combination and create shortcuts to system folders such as My Computer, Network Neighborhood, Dial-Up Networking, Control Panel, and Recycle Bin.
WinKey is freeware.
