Description michael 2020-11-06 14:49:06 UTC

SUMMARY
When scrolling horizontal using keyboard Kdiff3 scrolls view by one pixel, which is next to useless.  
It should scroll by multiple characters, i propose 8 or maybe percent of screen - 10-20% of screen?

How to reproduce:
1. Open any diff.
2. Use cursors left/right to scroll.
3. It takes forever to scroll long lines to right...

System:
Windows 10, x64, Kdiff 1.8.3 (from https://download.kde.org/stable/kdiff3/kdiff3-1.8.3-windows-64.exe)
