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.
To switch to the next tab, use :tabn, and to switch to the previous tab, use :tabp (short for tabnext and tabprevious respectively). You can also jump over tabs by using :tabn 2, which will move to the second next tab. To jump to the first tab, use :tabr (tabrewind) and to jump to the last tab use :tabl (tablast).
To directly move to first tab or last tab, you can enter the following in command mode: :tabfirst or :tablast for first or last tab respectively. To move back and forth : :tabn for next tab and :tabp for previous tab. You can list all the open tabs using : :tabs. To open multiple files in tabs: $ vim -p source.
You can use :tabclose (shortened alias also works :tabc ). Read more with :help tabpage . As for the buffer coming back with :bn , I believe this is normal for "hidden buffers", and :bn wraps around to the first buffer when you go past the last one. Save this answer.
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.
Fix the potential issue when a tab is closed:
" Switch to last-active tab
if !exists('g:Lasttab')
let g:Lasttab = 1
let g:Lasttab_backup = 1
endif
autocmd! TabLeave * let g:Lasttab_backup = g:Lasttab | let g:Lasttab = tabpagenr()
autocmd! TabClosed * let g:Lasttab = g:Lasttab_backup
nmap <silent> <Leader>` :exe "tabn " . g:Lasttab<cr>
I use buffers and not tabs, but I am able to switch between the current and latest used buffer using :b#
Basics of using buffers are:
:e filename to open file in new buffer
:bn to go to next buffer
:bp to go to previous buffer
:bd to close current buffer
