3.

Actual Results:  
Nothing happens

Expected Results:  
It switches between tabs like any other tab bar.
Comment 1 Kai Uwe Broulik 2014-11-13 18:58:42 UTC 
Re-assigning to ktexteditor framework since it's KateViewInternal::wheelEvent(QWheelEvent *) which does it wrong, it just checks for delta() larger or smaller than zero causing the slightest finger movement to trigger a line-scroll.
I looked into QAbstractScrollArea and the like code to find out how Qt internally handles it (especially with the Shift faster scroll), applications that do not override the scroll behavior like Konsole work fine but I did not find any clue there.

Btw., that doesn't fix the tabbar issue at all ;=)

The tab bar thingy is a kate application bug.
