any docs for all nodejs event API? [closed]

Question

I saw some code snippet like below:

process.stdin.on('keypress', function(c, key){          
if (key && 'enter' == key.name) { 

But sadly I couldn't find anything about how to use keypress event in node's docs. Obviously it's different from keypress event in browsers. Moreover there is nothing introducing what key object is, so I don't know how to use key.xxx or key.name == xxx to detect which key user is pressing.

What do I miss? There must be somewhere I can found how to use node...

The node documentation seems quite lacking in that regard like you mentioned.

The only reference I found was when going through the source for the 'readline'-module:

function emitKey(stream, s) {
    var ch,
    key = {
        name: undefined,
        ctrl: false,
        meta: false,
        shift: false
    },

and so on, basically the name, if ctrl is pressed, if shift is pressed, and some meta.

There's no doubt the docs needs some work :)
