Does Skyrim for PC support command line options

I can confirm that the main executable is not tied to Steam. Launching it directly start the game without going trough the "Loading game" steam window, and you can't access the steam community if you started it this way.

This was surely done to enhance compatibility with outside tools like Wrye bash or OBSE for oblivion. With Oblivion on steam, you can't launch the game trough an external launcher without going trough the vanilla launcher that steam launches.

Apparently, it was an oversight from either Bethesda or Valve, and was fixed in the first patch. (source)

There are two main console commands for quick teleport:

• coc (Center-on-Cell) expects one argument (the cell name) and teleports you there. Obviously, "Whiterun" is a cell, while "Dawnstar" isn't. This is for named (mostly interior) cells, and expects the name as defined in the Creation Kit. The UESP lists those - where known - as "Console Location Code(s)" in their location descriptions (see: overview of the Skyrim locations).
• cow (Center-on-World) expects three arguments: The world name (as defined in the Creation Kit) and the X- and Y-coordinate of the cell in question. Tip for orientation: the highest point in Skyrim is in the worldspace "Tamriel", along with most of Skyrim, at the coordinates 13, -13, so you can get there using cow Tamriel 13 -13. The UESP lists those as the exterior location coordinates, where known and applicable.
