I often have several files open in vim, each in a different tab. I have to remember which tab has which file open. Is there a way to show this in the tab titles?

vim supports tabs (both in the GUI and on the command line), so you do not need to use tabs from gnome-terminal. See :help tabpage. – honk Jul 3 '10 at 23:26
@honk: Thanks, that's pretty neat! I think I'm going to stick with gnome-terminal tabs, so that I can use alt + [tab number] to switch between them. Or is there a way to do this in vim, too? – Matthew Jul 4 '10 at 1:00
CTRL-PgUp/gt and CTRL-PgDown/gT for switching to next/previous tab, and also e.g. 2gt to go to tab 2. Not sure if the CTRL part is default or depends on the terminal setup. – honk Jul 4 '10 at 2:12
@honk: gnome-terminal steals CTRL-PgUp/PgDown when multiple terminal tabs are open (it works when vim is the only one). 2gt works, but neither option is as convenient for ant + [tab number] anyway. Thanks for the tip, though, I'll remember it if I'm ever stuck using a terminal without tabs. – Matthew Jul 4 '10 at 18:31

From vim.wikia.com:

Add this to your .vimrc:

let &titlestring = hostname() . "[vim(" . expand("%:t") . ")]"
if &term == "screen"
  set t_ts=^[k
  set t_fs=^[\
endif
if &term == "screen" || &term == "xterm"
  set title
endif

:set title is enough for gnome-terminal. – honk Jul 3 '10 at 23:25
For anyone curious: To make the title just the filename, change the first line to let &titlestring = expand("%:t"). – Matthew Jul 4 '10 at 23:45
