 ==== Mac OS X ====
 On Mac OS X (maybe on BSD systems in general), screen launches a ''login'' process which then executes the shell. Therefore, the id of the screen session (''$STY'') does not start with the parent processes pid (''$PPID''), but with the parent pid of the parent process. Therefor, you have to
-put this in your ''.zshrc''
+use the following lines in your ''.zshrc''
   case "`ps -o 'command=' -p $PPID`" in
   "login"*"zsh") pppid="`ps -o 'ppid=' -p $PPID|sed -e 's/^ *//g'`" ;;
