search with pasted text and C/C++ mode

[lehe <timlee126@yahoo.com>]

Hi,

My first question is about using Ctrl-s to search text in emacs. Firstly I
copy some string, then Ctrl-s, and now I Ctrl-y and hope to paste the copied
string as the string to search but it didn't happen. Instead some text has
been highlighted all the way till I exit emacs. Can someone please let me
know to do it correctly?

My following questions are about programming C/C++ in emacs:

When I use cscope in emacs to search some symbol, there will be a new window
created with lines showing all the positions where it appears. I try to
click each line in hope to jump to that particular position in some file,
but nothing happens. How could I jump from the search results from cscope?

When I program in C++, I will have a C++ drop-down menu (guess it is perhaps
from GNU indent or the original C++ mode of emacs?) at the toolbar of emacs
for .cc files, but will have C menu instead for .h files. Is it possible to
have C++ menu for both source and header files? Or this does not matter?

Thanks and regards!
