Why is it transforming ctrl+scroll to scroll differently (as @b4n pointed out on the code) instead of doing nothing when `scrollwheel_zoom_disable` is set?
On #2954 you say:
I have the editor font sent to a comfortable size. Many shortcuts consist of combining the Control key with others. And of course, the touchpad is used for moving the cursor. So very frequently (multiple times per day), I accidentally engage the scrolling function of the touchpad while the control key is pressed. This causes the editor view to zoom, which is disruptive.
Simply disabling the ctrl+zoom will achieve your aim and won't unexpectedly scroll the view either.
