This is a little useful trick for VIM users. As you may know VIM supports tabbed editing using the :tabnew command. It is then possible to switch between tabs using the :tabnext and :tabprev command. A faster shortcut is to add these two lines to the vimrc
nnoremap <F1> :tabprev
nnoremap <F2> :tabnext
Now you can use F1/F2 keys to switch between tabs.
