I´m running Windows 7 on my Macbook. Accidently I pressed a weird key combination: Shift + Apple + 4. It didn´t make a screenshot but instead i just starts a random application. What exactly is happening here?
Isn't it listed in this wikipedia ?
I am not entirely sure if the Apple key gets converted to Windows Key or Alt, Looking it up seems to state different things depending on the keyboard you are using.
In any way, Ctrl+4 is application dependent (e.g. In Chrome, switches to the 4th tab)
Excluding this, various combinations of Ctrl, Alt, Shift and Windows Key all do operations on the 4th pinned item on the Windows Task bar.
Operations include launching 4th pinned item, switching between the 4th item's open window and launching the 4th item's context menu.
