What path do you for setting up a keyboard shortcut?

settings>keyboard>application shortcut>add

Could you change your shell? Test it with gnome.

I'm new in this system, so is this a version error?

OK, So do this:
1) Logout or restart Kali
2) On the login screen select the username you want to login with that.
3) After selecting the username, In the right-bottom corner of the login screen, you can see a gear icon.
4) Click on the gear and select another shell

OR

If you have no other shell, you can do this:
1) Login to Kali
2) Open terminal and enter the command "sudo apt-get install lightdm"
3) Enter the command "sudo dpkg-reconfigure lightdm"
4) Restart Kali
5) In the login screen after selecting the username, clicks on the gear and select lightdm

Please note that: Personally I don't like Xfce yet so I don't use it and I like KDE and Gnome absolutely! :)
