Horizontal scroll speed problem in kdiff3 I use kdiff3 Version 0.9.98 (64 bit) on El Capitan.

When comparing files:


using ↑ or ↓ keys scrolls files by one line (one press or auto-repeat scrolls one line)
using ← or → scrolls files horizontally one pixel at a time


Is there a way to speed up horizontal scroll? For example one character (better yet 8 characters) at a time instead of pixels?
So for me I have a Magic Mouse, and side scrolling doesn't work. Because of how much I scroll around (for better or for worse) I always display the scroll bars in my windows. In kdiff3, I have a bar on the very bottom of the window that is horizontal, and if I use my mouse to click and drag, then it will scroll left and right for me much quicker than one pixel at a time. I still wish side scrolling worked, but for now, this works well.
