here is what I'm trying to solve. I have a crash dump from Google Chrome.
I open windbg and say File -> Symbol File Path: "SRV*c:\code\symbols*http://msdl.microsoft.com/download/symbols;SRV*c:\code\symbols*https://chromium-browser-symsrv.commondatastorage.googleapis.com" I guess this looks for the debugging symbols from let to right and should finally grab them from google then. I copied that from http://www.chromium.org/developers/how-tos/debugging.
I drag and drop the crash dump into windbg
And then...

This dump file has a breakpoint exception stored in it.
The stored exception information can be accessed via .ecxr.

^ Syntax error in '.excr'
You see that it says "The stored exception information can be accessed via .ecxr" but once I insert that it tells me that I have a syntax error.
Does anyone know what I'm doing wrong?
You've got a typo, it's .ecxr :) In the meantime, another easy way to get information out of a crash dump without needing too much WinDbg-fu, is:
.symfix; .reload
!analyze -v
And if this is a .NET App (Chromium isn't but just for extra info), add these three lines
.loadby sos clr
!pe
~*e !clrstack
