True, so it's handy to be able to toggle them on and off on a single
keystroke. I use F1, as it is easy to find. This vimscript in .vimrc
then implements the switch, in my case for _relative_ line numbers, as
they allow e.g. y7+ to copy current line plus the lines down to a chosen
point, without having to count the lines. That's a greater productivity
improver than just knowing you're on line 27423:

" Toggle relative line numbering.
function! NList_toggle()
    if &rnu == 1
     set nornu                " For absolute, elide the 'r'.
  else
     set rnu                  " For absolute, elide the 'r'.
  endif
endfun

To avoid stairstepped insert when pasting that here from the clipboard,
I have F12 mapped to:

set pastetoggle=<F12>         " <A-p> is easier. (See "Paste")

I tend to forget that I also have the alternative:

" Paste
" Paste without needing pastetoggle to avoid staircase text, due to ai always set.
" Works with "+y<motion> in another vim instance. Also avoids wrapping.
nnoremap <A-p> "+p
inoremap <A-p> ^["+p^Mi
nnoremap <A-c> "+y

(The ^[ is entered as control-v Esc, and ^M as control-v Enter, but you
knew that.)

<A-p> is Alt-p. Your choice of invoking key may differ.

So, yep, Vim does allow two-key chords, and the distinction from Emacs
reduces a little when you do that. Vimscript may look a little C-like in
places, but that can't be helped. (Awk is also significantly C-like.
Perl is much more successful at voiding the benefit of common language
know-how.)
