linux - Fast switch keyboard layout in Ubuntu (10.04)

I have 3 keyboard layouts in use. English, Arabic and Hebrew. To switch from English to Hebrew for example, I have to hit alt-shift twice (English -> Arabic -> Hebrew). I wonder if I can set-up something like [ctrl]-[shift]-1 to immediately switch to English, [ctrl]-[shift]-2 for Arabic and [ctrl]-[shift]-3 for Hebrew or something similar.

Thanks

You may use setxkbmap with xbindkeys.
Example of .xbindkeysrc:

#Switch to english
"setxkbmap us"
   0x4 + c:10
Control + 1
#Switch to russian
"setxkbmap ru"
   m:0x4 + c:11
Control + 2
#Switch to japanese
"setxkbmap jp"
   m:0x4 + c:12
Control + 3
