Usually I duplicate only 1 line, and in 100% of cases the cursor needs to be on the copied line to start editing it. But when duplicating more lines with a prefix arg, often it's expected to have the cursor on the top copied line to start editing copied lines top-down. I wonder if this is a common use case. > * A single-key binding (like H-y but not C-x y) makes quite > a difference because that way I can quickly stutter out copies as > needed without having to plan ahead and use prefix arguments. I don't believe everyone would agree on such short keys. Maybe better to try finding a key in the 'C-x x' keymap (that already contains a line-related binding 'C-x x t' `toggle-truncate-lines'). > * Rectangle duplication is very useful when editing tables or code > with similar structure.

There are already copy-rectangle-as-kill and yank-rectangle. OTOH, it seems 'M-w C-y' already can duplicate rectangle regions?
