I have zero patience when trying to make small adjustments to files, which is what my command line text editor should be for. Nano just has everything at the bottom in case you forget (I do, frequently) so the workflow is ridiculously streamlined for me
Well, if you dd+p you paste it back again, and then it's in the clipboard so you can p it in other places. In any case you can u(ndo) it without issues.
yy to copy, dd to cut, p to paste. Need to move 5 lines at once? No problem, move to the first line and use d5d, and p to paste it. Vim gets a bad rap for being confusing, but it's so fast to move text around once you get the hang of it.
