I found several plugins that crops the image, but doesn't have the uploading function.
Here are those plugins:
TMatthew JWindowCrop
imgAreaSelect
So, how do I put the uploading function on JavaScript, I heard you can use it as a "Server-Side Language" (node.js) or should I use a different language like PHP?
Try JCrop, files for download contains sample php script to get you started and many samples here on stack.

I'm creating a Zimlet to archive a message by pressing a key. For example 'a'.
Can anyone give me a hint how can I listen for this key?
Take a look at these blog entries:

http://blog.zimbra.com/blog/archives/2006/09/look-ma-no-mouse-keyboard-navigation-and-shortcuts-in-the-zimbra-collaboration-suite-and-the-kabuki-ajax-toolkit.html
Basically you need to add and register a keymap, than you can define key-handlers.

want these things when a function call :
1.Open a text file (not visible to user)
2.Select a Text which is to be change
3.change the text
4.And save it at same place.
This is not possible in JavaScript. JavaScript is sandboxed by the browser and doesn't have access to the local computer.
Also, what you're trying to do sounds dodgy, and may well be the exact reason why it's sandboxed.
