Hi everybody,
I could use some help here, please.

This is what I found in how-to's (the file referred to is xorg.conf in /etc/X11/):
============================================================================
5) if you need to install aditional layout( russian, for example), you need to add:
Quote
Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbLayout" "us,ru" ## KEYBOARD_MAP! #additional layout
Option "XkbOptions" "grp:ctrl_shift_toggle,grp_led:scroll" #Ctrl-Shift layout switching key combination
Option "XkbModel" "" ## KEYBOARD_MODEL!
Option "Xkbvariant" "" ## KEYBOARD_VARIANT!
EndSection
============================================================================
Instead of Ctrl-Shift, I would like to switch keyboard layouts with double-pressed Scroll-Lock key. What should I put instead of "grp:ctrl_shift_toggle"?
Many thanks!
