Switch to specific keyboard layout using Ctrl+Shift+Num

view story

http://askubuntu.com – What I want is to be able to press: Ctrl + Shift + 1 - switch to English keyboard layout Ctrl + Shift + 2 - switch to Hebrew keyboard layout Ctrl + Shift + 3 - switch to Russian(Phonetic) keyboard layout I've seen similar questions already asked here, but only answers I saw used setxkbmap which breaks the UI keyboard layout selector, which is something undesired. Thanks for any help. (HowTos)
