Change location.hash (1) without history entry, and (2) without scrolling the page

[abeall]

I'm attempting to implement some deep-linking in my simple AJAX application by setting location.hash, and I've run into two problems:

1) Sometimes setting location.hash seems to send the window on both IE and FF to scroll to the top of the page. I do not want any scrolling to occur. The location.hash change happens in a function which is triggered in an onclick event.

2) Changing location.hash creates a history entry on FF (not on IE)... that's pretty cool for FF, but in this case I do not want a history entry created. How can this be avoided?

I found an example which seems to have avoided both these problems, but cannot decipher the pertinent code:

Any help would be great. Thanks.
