Difference between extend_line_below and select_line_below?

[RoloEdits]

Both select the line if not already selected, and if selected will select the line below. What is the crux that differentiates them?

It addresses this: #9079

It can shrink the selection if you go the opposite direction (e.g. if you x one too many times, you can go shrink it).

Thanks. As far as I can see, this is a superset of the previous x key? Is there a need to have both?

The older command was kept for backward compatibility I think, probably many people are used to it. But I use the newer command too (#9080 (comment))
