gvim: switching tabs with keyboard
Use gt and gT commands.
:tabn and :tabp also work.
Read :help gt and read that section completely. There are many useful commands explained there.
Press gt to switch tabs. Also - 1gt 2gt to open 1st, 2nd... tab.
I have these mappings in my vimrc:
map <C-Left> <Esc>:tabprev<CR>
map <C-Right> <Esc>:tabnext<CR>
map <C-n> <Esc>:tabnew
I'm by no means a pro vim'er, but it works for me so I thought I'd share :) Control+Right for next tab, Control+Left for previous, Control+n to open a new tab (left out the so you can specify the path to open in the new tab).
