[SLUG] ask emacs

[henry]

Dear List:   I have 2 questions about Emacs under console, 1 questions about Xemacs under console : 1.  I use ct-x ct-f  to find file-A ,then ct-x i to insert file-B      then c-x 2 to list 2 files simultaneously in separate windows horizontally      ,but I get file-A,file-A,how do I get file-A,file-B?   2. How do I switch to c-mode  or text-mode ? (c-mode is used by c-programmer ,Commands under text-mode is almost the same as  fundmental mode)   3. How do I change options in Xemacs ?(I use   f10   to change options in Emacs)            BestRegards' Henry
