Locating the file that a function (not on the stack) was written in

This question came up in one of the internal aliases a couple days ago.  While debugging, how do I find the source for a particular function that is not on the stack?  There are a couple caveats to consider first:

1. You must have symbols that include source information (public symbols have this information stripped out of them)
2. You must have turned on loading source information.

To satisfy #2, first run .lines -e and then you have several choices:

• use ln with name of the function
  • 0:000> ln RuntimeTest!CUIElementName::CUIElementName
    d:\dev\acw\enduser\nuiux\acw\activecontentwizard\unmanaged\property.cpp(1593)
    (00857050) RuntimeTest!CUIElementName::CUIElementName | (008570e0) RuntimeTest!CUIElementName::AddRef
    Exact matches:
    RuntimeTest!CUIElementName::CUIElementName (void)
• use u with the name of the function
  • 0:000> u RuntimeTest!CUIElementName::CUIElementName
    RuntimeTest!CUIElementName::CUIElementName [d:\dev\acw\enduser\nuiux\acw\activecontentwizard\unmanaged\property.cpp @ 1593]:
    00857050 8bff mov edi,edi
    00857052 55 push ebp
    ...
• use lsa with the name of the function and then lsc
  • 0:000> lsa RuntimeTest!CUIElementName::CUIElementName
    ...
    1590: }
    1591:
    1592: CUIElementName::CUIElementName()
    > 1593: {
    ...
    0:000> lsc
    Current: dev\acw\enduser\nuiux\acw\activecontentwizard\unmanaged\property.cpp(1599)
