Scroll Lock led

  Sorry for my stupidity :-), but how can I configure xkb to have a more 
appropriate behavior
for Scroll Lock?
  I learned that I could use it with something like:

Section "InputDevice"
    Identifier "Keyboard"
    Driver     "kbd"
    Option     "XkbModel" "abnt2"
    Option     "XkbLayout" "us,br"
    Option     "XkbOptions" "grp:alt_shift_toggle,grp_led:scroll"

in xorg.conf

  And use Alt+Shift to toggle layout from/to us and br and have the 
Scroll_Lock led to show the state.

  But what about when there is no function assigned to Scroll Lock, or 
even better, how to give it a default behavior. I found out that Konsole 
checks when Scroll Lock was pressed, and doesn't do any output until it 
is pressed again, and maybe other applications use it to temporarily 
disable scrollbars and the like... But then, xterm and gnome-terminal 
uses Ctrl+S and Ctrl+Q, while Konsole ignores it.

  I tried a few experiments attempting to create some custom option in 
that would use any of the usr/share/X11/xkb/compat/ledscroll "maps", 
i.e. things like:

 grp:scroll_toggle     =       +ledscroll(scroll_lock)

  Well, I dont understand it very well, just guessed. If someone has an 
alternative/work on it I would like to know.

  Maybe this isn't very appropriate for a graphical interface, but if it 
worked like in a console, where Ctrl+S sets the Scroll Lock led and 
Ctrl+Q unsets it, would also be interesting.
