Is it possible to jump to a user specified move (by programming means) after the Go board is loaded?

Do you mean through a link? It is possible to link to a specific move, for instance in the recent game:

http://eidogo.com/#titles/38misf11

I can link to move 50 by adding :0,50 at the end of the URL

http://eidogo.com/#titles/38misf11:0,50

If I really wanted to I could use this mechanism to skip around to a specific move in the game once I have the page loaded by making it :0,## with ## being the move number I want.

Thanks for your information. That seems to work on Eidogo server only. I tried both URLs and their source code are identical. So the extra info is not passed to the Go client by a parameter. Probably the URLs are parsed inside the Javascript code.
