Most PDF viewer software on M$ Win can scroll sideways with the Shift key pressed. How do you make Okular scroll sideways with the mouse wheel? Most of my work requires reviewing construction drawings, which have many details on A0-size pages. Please!
Unfortunately, Alt+Wheel doesn't work. It does the same as Wheel only. This is how it was forever. I'm not in fit page or fit width mode, no. Never worked with older versions, nor with the latest plasma Fedora 40 KDE spin where Plasma 6. All my mice with a single wheel and do not tilt. I'm out of luck.
