LustyJuggler is a Vim plugin that allows you to switch very quickly between your active buffers. LustyJuggler is a high speed buffer juggler. Having to consciously think about which buffer you need to switch to sucks, so use this instead.
Launch the juggler with either of these key combos:
< Leader > lj
< Leader > lg
The command bar at bottom is replaced with a new bar showing the names of your currently opened buffers in most-recently-used order.
The buffer names are mapped to these keys:
1st --> a or 1
2nd --> s or 2
3rd --> d or 3
4th --> f or 4
5th --> g or 5
6th --> h or 6
7th --> j or 7
8th --> k or 8
9th --> l or 9
10th --> ; or 0
So if you type "f" or "4", the fourth buffer name will be highlighted and the bar will shift to center it as necessary (and show more of the buffer names on the right).
If you want to switch to that buffer, press "f" or "4" again or press "< ENTER >". Alternatively, press one of the other mapped keys to highlight another buffer.
If you changed your mind, cancel the juggler with any of "q", "< ESC >", "< C-c >", "< BS >", "< Del >", or "< C-h >".
Copy the script into your $HOME/.vim/plugin directory so that it will be sourced on startup.
NOTE: This plugin requires Vim be compiled with Ruby interpretation. If you do not currently have this functionality, see the "Install Details:" section of the script for directions on adding it. It's not too tough.
