keyboard shortcuts not working systemwise

I use OpenSuse 13.2 with xfce desktop environment. I noticed that keyboard shortucts ar enot working systemwise. Consequently, I have to do copy/paste and other activities using my mouse instead of keyboard. openSuse 12.3 with xfce on teh same laptop worked fine with keyboard shortucts.
Please advise. Thanks

I changed in hardware settings the keyboard model.Instead of Toshiba Satellite keybaord which I expected to work well since I use Toshiba Satelite laptop i cahnged to Microsoft Natural Keyboard Pro USB and now everyting works well. Maybe some fix to driver is needed since obviously Ctrl key did not work with Toshiba hardware keyboard setting.
