For more information and FAQ go to http://fluxbox.sourceforge.net

To disable tabs and/or iconbar just  change it in configure menu.

To use your own configuration:
Create a directorory, in your homedir, called .fluxbox
and copy: init, keys and menu from fluxbox datapath.
Dont forget to change session.menuFile and session.titlebarFile
in the file init.

You can use your old blackbox configuration file too. Just copy
.blackboxrc to ~/.fluxbox/init . The same goes for menu file.
You can also use the Blackbox themes in Fluxbox.
If there isn't any format for the tab in the theme then
the tab will have the same theme as the titlebar.

The keys config file can be selected in the file init:
session.keyFile: <filename here>
The keys file is no longer compatible with bbkeys. There's a convertkeys
script at http://fluxbox.sourceforge.net/ that will convert the bbkeys
format to the fluxbox format.
 
 
A few extra notes:
 - To disable tabs and/or iconbar just change it in configure menu.
 - To work with tabs, use the third mouse button to drag a tab to another tab.
   This will group the two windows together.
 - With 'Sloppy Window Grouping' turned on (in your configure menu), you can
   drop the tabs anywhere on the target window to group windows together.
 - The 'Maximize over Slit' option means that maximized windows will not stop 
   at the outside border of the slit, and will instead cover it.
 - In the init file, the session.screen0.rootCommand: option will override
   the rootCommand option in a theme- keeping your background the same, no
   matter what the theme says it should be.
