How can I turn my keyboard short-cuts back on in SPSS?

I have somehow managed to turn off my keyboard short-cuts in SPSS so now I can not copy and paste my data as usual between SPSS and Excel using ctrl+c, I have to right click which is not too bad but a bit of a pain as I am more of a keyboard user than a mouse user! My keyboard short-cuts all work in my other programs I am running, just not SPSS.
