Re: copy-line

Comparing Vi/Vim to other editors is not fair ;-)

Vanilla Emacs has no way to copy text that has not been marked.  Thus, to copy 
a line, you have to mark it first.  The complete sequence is:

C-a C-Space C-e M-w

In alternative, you can kill a line and yank it back at once:

C-S-Backspace C-k

Unlike Vi, the line will be copied/killed without its new line.  I don't know 
whether such behaviour is customizable.

Cheers.
