Excel 2007 : Quick Access Toolbar

My company recently upgraded to Office 2007.

As such, am learning about the Quick Access Toolbar (QAT).

I have customized my QAT to contain the things I need.

PROBLEM: When I use a differant computer, my customized QAT does not follow me, it displays the standard QAT.

QUESTION: How can I get my customized QAT to be transportable? Is there a file that is updated for the QAT that I could copy and use?
