Suppress Enter don't work when using echo_newline extension

I’ve tried

keypress : function(event) {
   if(event.key === "Enter"){
      event.preventDefault();
      event.stopPropagation();
      return false;
   }
},
keydown : function(event) {
   if(event.key === "Enter"){
      event.preventDefault();
      event.stopPropagation();
      return false;
   }
},
keymap : {
   ENTER : function(event){
      event.preventDefault();
      event.stopPropagation();
   }
}

but pressing ENTER still makes a new line in the terminal.

TODO:

• fix echo_newline keymap option with ENTER
• fix echo_newline keymap method with ENTER
• document workings of keymap and events.

The PR was merged to only documentation the working on events is needed here.

I think my PR will handle bullets 1 and 2 in the TODO here.
