migrating from Autocad

Sorry guys, am massively lost in this "Community".....

Thought I had posted this, now can't find it.....

Am looking at what has to happen for me to migrate across from Autocad,

Q1: Autocad shortcut command references are held in a file called "acad.pgp", what is this file called in Draftsight, where can I find it, can I modify it...?

cheers,

Stuart.
