Yes, that's almost right =)
(I wrote "u" and "f" not "U" and "F", but the result will be the same.)

Yeah, that's pretty screwy terminology. Why not use terminology like
delete, copy and insert?
at least that makes sense ... even if the terms cut and paste didn't
exist back then.
Interestingly, Visual Studio has Emacs emulation. I don't know how far
it goes, though. But, I suppose if you're used to doing things the Emacs
way it could be very useful.

It is likely that you have a keyboard where Emacs regards the Esc
key as the Meta key.

Have a look at this:
http://www.gnu.org/software/emacs/manual/html_node/emacs/Rectangles.html
(The text cursor is the "point" and you can put a "mark" in the text with C-space.)

Emacs can do this. Probably many decent editors can. Define a macro
that does it to one line (and then moves down a line). Then tell it to
execute the macro 10 times.

You can use rectangular editing to add space for that column. Then just
change from insert mode to overwrite and add in the numbers.
Alternatively, in a separate buffer, type in that column. Then use
rectangular editing to copy that rectangle, and yank it into the text
that you want.

It's an old, old feature.

Oh come on! This is the lamest of your complaints. If it was written as:
Ctrl-u 10 Ctrl-f
OR
^u 10 ^f
You'd get it. But C-u 10 C-f? *That's* creating problems for you?

No stranger than cut and paste. In emacs, deleting a bunch of text is
the same as putting it into the "clipboard" (kill buffer). So kill makes
sense, because that's really what you may be doing - just deleting text.
Yank simply yanks the text from the kill buffer where you want it.
Cut? Makes sense for papers, but not for screens.

So here's what you could do:
M-g g // goto-line
2 // 2
C-right // forward-word
C-right // forward-word
C-space // set-mark-command
down // next-line
down // next-line
C-x r t // string-rectangle
$ Just //
