Alt+tab on Fluxbox

view story

http://askubuntu.com – I've been using fluxbox on my netbook, and have been very pleased. That is, with everything but one feature. I would really like it if I could use fluxbox with the added functionality that when I use alt+tab it will show me the windows I am switching between. (As it does in Windows/Mac/GNOME/KDE/Xfce/...). Is there some app I can install that would do that? Or is the only resort to use a different GUI? (HowTos)
