Using another editor with Unity - rather than UniSciTE

How do you set Unity to load another editor, other than UniSciTE, when you click on the scripts in your project pane.

Also, how do you set your third party editor to recognize Unity Javascript and its various classes, functions, etc?

There's quite a couple of pages on this subject:

Here's one for Visual Studio:

Here's one for UnityDevelop (my personal favorite):

Here's one for the UnityScript Editor :

And if you scour the forums, you'll surely be able to get Notepad++ to play nice with Unity's implementation of Javascript.

Just go to:

Edit -> Preferences -> External script editor. And then find you script editor.

Adope Extended Script editor is a great program for scripting. :)
