XKB dirty way

gistfile1.txt

To see current keyboard mapping: setxkbmap -print 
To understand what it means: see Ivan Pascal's documentation on right way to do it.

cd /usr/share/X11/xkb

In file keycodes/evdev swap:

<CAPS> = 66;
<ESC> = 9;

and

<LALT> = 64;
<LCTL> = 37;


In file symbols/ru:

numerosign to numbersign :)


Layout switch I'm still doing in Gnome widget, though all this including it must be done in one clean manner, may be some day... ;)
