Question

I saw this same question for VIM and it has been something that I myself wanted to know how to do for Emacs. In ReSharper I use CTRL-D for this action. What is the least num

Answer 1

I have copy-from-above-command bound to a key and use that. It's provided with XEmacs, but I don't know about GNU Emacs.

`copy-from-above-command' is an interactive compiled Lisp function
-- loaded from "/usr/share/xemacs/21.4.15/lisp/misc.elc" (copy-from-above-command &optional ARG)

Documentation: Copy characters from previous nonblank line, starting just above point. Copy ARG characters, but not past the end of that line. If no argument given, copy the entire rest of the line. The characters copied are inserted in the buffer before point.
