SUMMARY

SumatraPDF is a PDF viewer that allows all of these with a single hand with the mouse:
- Move/drag the page
- Zoom
- Select text

OBSERVED RESULT

Okular allow the same using the browse mode.
But the zoom is implemented with middle click + move the mouse instead of left click + wheel.

EXPECTED RESULT

click + wheel is what SumatraPDF implements and this make really easy to zoom in while adjusting the view on the particular thing we want to zoom by draging the mouse while zooming.
This is also faster than middle click + moving (sometimes alot) the mouse to zoom in on a small thing.

Currently, the zoom does not follow the mouse, the would require something like https://invent.kde.org/graphics/okular/-/merge_requests/134.
