Select all poly faces with mel script/command?

My mel knowledge is failing me. This seems easy. I select a poly object. Now what is the command to select all it's faces (or any other component for that matter?)
Thanks

I can answer my own post:

polySelectConstraint -m 3 -t 0008; will work for faces


PolySelectConvert 1;

will do it too. (or 2 for edges, 3 for Vtx and 4 for UVs)

Right on. I figured there were multiple ways to do this. Thanks.
