For years I remain lazy and didn't learn the basics of editing. Just the
I for edit and
ctrl+x. But I learn that you can do much more with some simple tricks.
I was a heavy user of emacs but I never had a preference in the war between Vi/Emacs. I mostly use Red Hat based operating system (RHEL, CentOS or Fedora) so I start to use vi by default since it's the default text editor package.

v then press
y to copy,
d to cut, move where you want and then press
p to paste.
