SUMMARY

I am reading material that has a multicolumn layout, or a book scanned from facing pages. To read it I need to zoom in so that a column is legible, then read down the page, then scroll up and to the right to find where the column continues. The last part, scrolling right, is the difficulty. It would be nice if there were a way to scroll left or right from the keyboard, (by screenfuls, rather than the small increments given by arrow keys.)

STEPS TO REPRODUCE
1. Zoom in so that horizontal scrollbar is shown.
2. Press (e.g.) Home or End
3. Open Settings -> Keyboard Shortcuts and look for "Scroll Page Left" and "Scroll Page Right"

OBSERVED RESULT

No effect in UI.
No such entries are listed in Keyboard Shortcuts.

EXPECTED RESULT

View should scroll left or right in increments of most the width of the viewport (with some overlap).
The shortcuts should be configurable in Keyboard Shortcuts.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Linux Mint 20.2 (Cinnamon desktop)
KDE Frameworks 5.86.0
Qt 5.15.3 (built against 5.15.3)
The xcb windowing system

Same use-case, same issue for me. There is more discussion in the older bug (343910), so I marked this one as a duplicate.
