I recently started using DraftSight and was delighted to see that most of my past AutoCad knowledge applies.  In particular, simple keyboard commands seem to be the same.  For example 'l" for line, "tr" for trim, "c" for circle, etc...

This has been true for DraftSight loaded onto my apple desktop, but when I loaded it on my apple laptop, it does not recognize any of these commands.  Is this a setting that I can turn on?

Thank you in advance.
