A while back the guys at unity released a version of their editor with macros enabled (by accident) in the current version is has been removed/disabled. (this because it’s something they use for testing and not meant for production environments)
But with recent endeavours I found it’s possible to enable it in the editor making debugging stuff within the editor more entertaining, plus it adds a new window to the editor making your editor more of an editor.
Please note this is not documented by unity and probably not supported either.

Simple script:

How to use:
Place this script in an Editor directory in your Assets and then:
Go to Window->Macros and tadaa.. you have a new editor window that can record all your editor actions and execute new ones.
May this help you on your endeavors of making cool new stuff for unity
