In most applications, one can scroll horizontally using a combination of holding Ctrl/Shift and using the scrollwheel. And in most applications, one can also scroll horizontally by nudging the scrollwheel sideways if the mouse has that feature (mine does).
But in Excel, I cannot find for the life of me, how to scroll horizontally, other than by dragging the scrollbar. I'm only using the mouse - atm I don't use my touchpad and I don't have a touchscreen.
So it's 2019 (for those not yet up to speed), and we have to drag a scrollbar. Srsly? Click and hold on the scrollbar, and drag it back and forth. In 2019.
Please, gentlemen, make Shift+scrollwheel AND sideways scrollwheel work in Excel 365 please. It's
really not that difficult. Both these features have been commonplace for a very long time, and of all Office applications, if there's one application where horizontally scrolling is common, it'd be Excel.
Please also note that this is not dependent any what kind of mouse I got. I got no drivers installed other than whatever Windows installs for me by default. Scrolling sideways has been a standard Windows feature since at least several years. Also note that
it works in all other applications that listen to the "horizontal scroll" message from Windows, so my hardware+drivers are perfectly sorted.
