Maybe I have misunderstood the OP's question.

Its the result of the command `semantic-symref-symbol'. It looks up your 
symbol in all your project include paths and presents all references to 
the symbol as links. You can jump to it with `RET' or you can view with 
`<space>'. In this case the symbol was a handy method I had written.

There is a similar function for tags with a small difference, instead of 
presenting it in a buffer, it cycles through all the matches in a 
"completion like" buffer. All of this is of course with the CVS version 
of CEDET.

Is that what the OP was looking for?
