because we're using exists(), turning it off with !s:RN only
works once -- here's my implementation:
nnoremap <silent> <Leader>rrr :silent call ToggleRltvNmbr()<CR>
function! ToggleRltvNmbr()
if !exists("s:RN")
let s:RN = 1
RltvNmbr
else
unlet s:RN
RltvNmbr!
endif
endfunction
and i used my spiffy new relative numbers to yank the
function for pasting here -- i love it!
i may make RN buffer local, so i can use this in other
buffers in the same edit session without having to hit the
toggle three times, but already this is wonderful
thanx again charles
