A couple of questions about the guide , these are from a Windows user perspective , very little  Linux experience . There are certain key commands that i do not understand .
First i get to here .
chmod 777 babyd
./babyd
ctrl+c  out
what do i press ? ctrl+c  out . Is out ESC ?
I then get stuck here .
vi /root/.baby/baby.conf
What keys to save the changes in VI then  exit ?
I also need commands to check it is then running ok in the VPS .

I also now get  :~/BABYCHAIN-Linuxdaemon-64bit# ./babyd
-bash: ./babyd: cannot execute binary file: Exec format error
