Does anyone have an #idea on how to stop #scrolling as soon as a #key is pressed? 
Let's say I'm on a website, scroll down (2-finger-#swipe on #touchpad) , and while scrolling I close/switch the #tab (both include pressing #ctrl). But as it's still scrolling -> in conjunction with scrolling the browser decided to zoom - at the current tab, as well as on the next tab...
This happens sufficiently often, to make me insane! 
Thus, I'm desperately looking for help

Mmm, maybe activate proper touchpad gestures, like 2-finger pinch zoom?
@FreakyBytes
Mmh, that would just get me yet another way to #zoom..
The browser would still zoom in #ctrl+#scroll, wouldn't it? 🤔
@martin
Ah, yes. I think I misjudged your problem. You want ctrl+scroll to not zoom in the browser? How about custom keyboard hooks on system level? (Now I'm getting ridiculous - I know ;P)
I know that in Firefox you can disable ctrl+scroll=zoom, I did that because it drives me insane and I use ctrl a lot to open new tabs.

#thanks for the hint! just disabled it by setting #mousewheel.with_control.action to 0 in #about:config
(0 means "Do nothing", 1 means "Scroll contents", 2 means "Go back or forward in the history", 3 means "Zoom in or out the contents")

This should do the trick for me, as I somehow only experience this problem in #firefox..!?
