Bug Description

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

Don't use CTRL. Use only super + w. It has probably something to do with key release rather than key press. So anything with ctrl or shift is not working properly. Ubuntu recently removed that patch from latest xorg which just landed in 16.04 through xenial. See LP: #1683383

Confirmed indeed, Marco do you think you could have a look to see if that's a compiz/unity issue and it would be easy to resolve?

Khurshid, to be clear, the CTRL and the W were the intentional keys, the Windows (aka Super) key was the complete accident that turned this into a real annoyance. Instead of one word being deleted, entire windows are removed. (The irony of course is thanks to mosh+tmux, the word was still there once I reconnected to that computer.)

If you hold down the Windows (Super) key in Unity, you'll see a handy menu of shortcut keys, where Super + W is used in four different items. If suddenly only one of them is supposed to work, it'd be nice to amend the menu of shortcut keys, though that'd probably be best served by a different bug.

Thanks
