Draftsight Shortcut Commands

I am using Draftsight on two machines. Pro 64 on a desktop machine and Draftsight Free on a laptop.On the Pro Desktop Version I can use shortcuts such as "DI" for GETDISTANCE. On the Free Laptop version if I use "DI" I get an "unknown command" error. I'm assuming that there is a shortcut menu or program that needs to be enabled. Where can I find this or is there another solution. Regards PW
