Question

In Vim, is there a way to quickly toggle between the current tab and the last-active tab? Sort of the way '' toggles between the current line and the last-active line. Plugins / keyboard mappings / voodoo all acceptable.

Answer 1

Put this in your .vimrc:

if !exists('g:lasttab')
  let g:lasttab = 1
endif
nmap <Leader>tl :exe "tabn ".g:lasttab<CR>
au TabLeave * let g:lasttab = tabpagenr()

Then, in normal mode, type \tl to swap to the tab you viewed last.
