I have recently changed desks in my office and moved to a different machine. Previously on my old machine with Autocad 2017 I go to Tools > Customize > Edit Command Aliases (PGP), to change my keyboard set up. This computer uses AutoCAD 2013 and this option doesn't appear in the Customize tab. Is editing command aliases a feature that was not supported for this version? or is there another way I can achieve this? I would like to keep the AutoCAD 2013 because it is a permanent license.

Thanks in advance for your help!
