Creating a Custom Shutdown Menu in Fluxbox

This is easy.

Just edit fluxbox "keys" inserting a line like that:

Mod4 x  :CustomMenu "path-to-menu"

Of course the menu you're pointing at must exist in ~/.fluxbox.

In my case, I've done that:

$ touch /home/pibarnas/.fluxbox/sair

$   echo "[begin] (Sair) \n \t [exit] (Sair) {Exit} \n \t [exec] (Desligar) {/sbin/shutdown -h now} \n \t [exec] (Reiniciar) {/sbin/shutdown -r now} \n [end]" > /home/pibarnas/.fluxbox/sair

$ cat /home/pibarnas/.fluxbox/sair

[begin] (Sair)
         [exit] (Sair) {Exit}
         [exec] (Desligar) {/sbin/shutdown -h now}
         [exec] (Reiniciar) {/sbin/shutdown -r now}
 [end]

My ~/.fluxbox/keys related line:

 Mod4 x  :CustomMenu /home/pibarnas/.fluxbox/sair


Now when I click windows button+x this menu appear:

You can make custom menus other than the default one as you wish. Hope you like the tip!
