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 number of commands to perform this in Emacs?
I use
C-a C-SPACE C-n M-w C-y
which breaks down to
C-a
: move cursor to start of lineC-SPACE
: begin a selection ("set mark")C-n
: move cursor to next lineM-w
: copy regionC-y
: paste ("yank")The aforementioned
C-a C-k C-k C-y C-y
amounts to the same thing (TMTOWTDI)
C-a
: move cursor to start of lineC-k
: cut ("kill") the lineC-k
: cut the newlineC-y
: paste ("yank") (we're back at square one)C-y
: paste again (now we've got two copies of the line)These are both embarrassingly verbose compared to C-d
in your editor, but in Emacs there's always a customization. C-d
is bound to delete-char
by default, so how about C-c C-d
? Just add the following to your .emacs
:
(global-set-key "\C-c\C-d" "\C-a\C- \C-n\M-w\C-y")
(@Nathan's elisp version is probably preferable, because it won't break if any of the key bindings are changed.)
Beware: some Emacs modes may reclaim C-c C-d
to do something else.
