The :RS /pattern/subpattern/{flags} command+function as shown below allows one to repeat a RS-substitute after the current cursor position.
For example:
" The cursor position is indicated with '^' on next line.
one two three one two three one two three
^
:RS /two/TWO/
one TWO three one two three one two three
^
move cursor:
one TWO three one two three one two three
^
(I think tip author intended to repeat :RS here?)
cursor ends up:
one TWO three one two three one TWO three
Put the following into your vimrc if you'd like to be able to do this.
" RS: repeat substitution command
com! -range -nargs=* RS call RepeatSubst(<q-args>)
" RepatSubst:
fun! RepeatSubst(subexpr)
if a:subexpr != ""
let g:repeatsubst= a:subexpr
endif
let curcol= col(".")
let sep = strpart(g:repeatsubst,0,1)
let pat = substitute(g:repeatsubst,'^.\(.\{-}\)'.sep.'.*$','\1','')
s/\%#./\r&/
let curcol= curcol + matchend(getline("."),pat)
exe "s".g:repeatsubst
norm! k
j!
exe 'norm! '.curcol.'|'
endfun
