Feature request: slow scrolling with Alt+j and Alt+k to match Alt+up-arrow and Alt+down-arrow
Summary
Slow scrolling only works with the arrow keys, and it would be nice if it also worked with the j and k keys.
Description
Currently you can scroll up and down with normal speed by using j, k, up-arrow, and down-arrow. You can also scroll with a slower speed (i.e., a shorter span of the page at a time) by using Alt+up-arrow and Alt+down-arrow. However, Alt+j and Alt+k do nothing. It would be great if this slow scrolling with the Alt key also worked with the j and k keys.
