Re: split windows side by side in emacs?

"how can i split windows side by side in emacs?"

c-x 3     (obviously!  

Actually the way to find this is to run the "apropos" command...

c-h a

And then type in "split" or something and it will tell you the command
"split-window-horizontally" is bound to the c-x 3 key combination.

"and c-x c-f is find file for me in windows. how do i create anew one?"

Not sure what you want, but

c-x 4 f

is bound to find-file-other-window.
