I want the same smooth scrolling behavior as current Chrome/Edge(mium) versions: snappy touchpad scrolling without delay, but smooth and slower scrolling when using the arrow keys on the keyboard.
Right now, in Firefox 73.0, I can either:
- Enable all smooth scrolling, which makes arrow-key scrolling pleasant, but touchpad scrolling annoyingly slow and unnatural.
- Disable all smooth scrolling, which lets me lets me "grab" the page intuitively with the touchpad, but leads to instant discontinuous jumps when arrow-key scrolling, making text harder to follow.
How can I enable smooth scrolling only for keyboard controls?
