Help setting command line shortcuts

Hi,
Does anyone know how to set command line shortcuts, maybe this is the wrong term…

At my work computer I can just type “PL” for polyline “D” for distance “C” for copy etc.in the command line but on my home computer these all do different things, I need to type out POLYLINE. Frustrating moving between machines,
any thoughts?
thanks
