KDE4: assign custom action to middle click on taskbar item
 

I want window to be closed when i middle click on the corresponding taskbar item. Can this is be configured in KDE4?

I cant find anything on google.

It doesn't look like it to me, unless something has changed in the most recent updates.

But of course kde3 has it.

That's one of my big complaints about kde4. While it does have many really nice new features of it's own, there are so many little things like this that were not carried over from kde3. And it was being able to configure the little things that made me choose kde in the first place.
