Qliner hotkeys is a free and open source keyboard productivity environment. It is the first product of its kind that is usable by computer geeks and non geeks alike.
Hotkeys builds on the concept of Windows shortcut keys but takes this concept to a whole new level. Do you think key combinations are hard to remember? Just hold the Windows key for three seconds and up pops a on screen Keyboard with icons on the keys that are configured. This you can use , not only to remind you of hotkey combinations, but also for Drag and Drop Configuration.
Hotkeys is smart in the way it launches applications and opens documents. When a key combination is pressed hotkeys will first try to find an existing instance of the requested application or document and bring that to the front. This behaviour can be overruled by holding the Alt key, which ensures that a new instance is allways launched. If no existing instances are found a new instance is started. If multiple instances are running the Instance Switching menu is displayed.
