if I have

one two three four

on the clipboard, can I paste it in front of (line by line)

duck cows chickens geese

I don't think so, but if you have a *rectangular* selection on the clipboard it'll paste in front of the "duck" in the manner you're seeking. So either option-drag around the words in question (one two three four), and then simply paste in front of "duck" (or even just drag the selection into place), or you can use keyboard selection techniques to establish the rectangular selection. For example, with cursor at the start: select "one" with shift-option-rightarrow, then click the option key to select rectangular mode, then (with shift held down) use the arrow keys to extend the selection. Anyway, hopefully this'll get you started down a route that fits your fingers!
