Oh, really? I remembered as so. Just my memory is wrong or macOS's behavior has been changed (IIRC, starting Sierra, mouse scroll event behavior has been changed, it might be changed at this time). > > which only supports vertical wheel operation but the user's device is > > obviously supports horizontal wheel operation in this case.

On Windows, native event doesn't support diagonal scroll with an event. So, this case never occurs on Windows actually. (If user tries to scroll content diagonally, both vertical wheel event and horizontal wheel event are fired separately.) Although, it could occur with some touchscreen. However, I don't see wheel events when I scroll content in Gecko with my notebook's touchscreen. (Pan gesture could fire wheel events, but I'm not familiar with this path: https://searchfox.org/mozilla- central/rev/1a4a26905f923458679a59a4be1e455ebc53c333/widget/windows/nsWinGesture.cpp#393,409-410,412-413 ) I'm not sure about GTK. GTK3's event has both delta values in an event. So, it could support diagonal scroll, but I don't have environment that Linux is installed on real machine (not virtual machine). Anyway, I don't think that we should use this feature when the user's device is obviously non-legacy pointing device, i.e., it supports diagonal scroll.

Firefox is missing this very convenient page-navigation short-cut. Use Case: As my eyes age, I find myself always scaling up the web pages I read (by holding down crtl and scrolling my mouse wheel). Doing this, often makes the page exceed the width of my monitor (hiding the right-side of the text I want to read) and produces a horizontal scroll bar at the bottom of the page. At this point, since I've already used ctrl-scroll-mouse-wheel to magnify the page, it would be wonderful if I could use shift-scroll- mouse-wheel to horizontally-scroll the magnified page and therefore center the (previously cropped) text that I am wanting to read.
