Hi, I just saw this behaviour and i believe its wrong (bugged), do the following steps to reproduce it:
* type:
a1
b2
* select both lines
* split selection into lines cmd + shift + L
* use the "Delete to EOL" macro => ctrl + k on Mac
* then "yank" it => ctrl + y on Mac
the lines are inserted in reversed order.
Is that the right/desired behavior?
Thanks,
