Hello, the key sequence ctrl + super + w is supposed to show all the windows in the current workspace of the type of the focused application. If you 'tap' this combination, that's what happens.
However, if you hold down this key combination for too long (perhaps 250ms?) it will proceed to destroy windows. After destroying all the windows of the application type, it will then focus the 'next' application and destroy that, too.
I've had this happen entirely by accident several times when trying to use ^W to delete words in a terminal.
Thanks
