how to keep/restore my view and mode?

[Leo.Hou]

Dear all,

I am not sure if I am using the right term of "view" and "mode". My
problem is as follows:

I am using C-x 3 and "follow-mode" to view my source code. Every time I
compile, the other column becomes the result of make. I need to use a
lot of keys to switch it back to normal: C-x o; C-x k; C-x o; M-x
follow-mode
Is there a better way?

And I'd also want to know how to kill the buffer in the other window
without switching to it by C-x o

Thanks in advance

Leo
