Re: vim: toggle between tabs and toggle between buffers

I tried these pseudo-codes, but these are just 1 time thing and won't change over time...couldn't figure out a good way.

;if more than one tab, don't hack

if tabpagenr("$") > 1

  unmap gt

  unmap gT

;otherwise , if there is one tab, use gt,gT,Ngt to switch between buffers

else

  if v:count == 0

    map gt :bn<cr>

    map gT :bp<cr>

  else

    map gt :<C-U>exec "b" . v:count<cr>

  endif

endif

Use v:count or v:count1. Knowing that "2:" results in ":.,.+1" you may also extract count using ":function Func() range" or ":command-range".
