Hotkeys can really speed up the daily working routine in Windows. Instead of using the start menu, shortcuts on the desktop or the Windows Explorer you simply press a few buttons which start the software automatically.
I recently discovered Qliner Hotkeys which is in my opinion close to perfect. The real advantage of Qliner Hotkeys is that it displays a graphical keyboard of all hotkeys currently in place. Users can drag and drop softwares around and browse their system for applications to add to spare keys.
