thanks Adams, I'll read the manual carefully.

btw, I'm using your elisp library and having my pop-up-frames variable
default setting to t,
Recently I'm trying IDE-like 'nav' mode from google code, and the
setting of pop-up-frames
starts conflict with nav, because for 'nav' it's better open files in
same frame. So this question
occured.
