Keyboard Maestro is a program that provides you with a simple and quick way to manage macros. You can use this utility to create your own macros to execute various types of actions, such as launching certain Mac tools, opening documents from your computer, accessing a website in your default web browser, etc.
This tool is definitely a must-have for power-users as it helps them complete various types of tasks with just a few clicks. Still, you don't need much computer experience to work with this program, especially since it provides you with plenty of useful instructions and easy-to-configure settings.
You have access to several sample items which can be tested, an efficient search tool, and a menu in your status bar from where you can change the way Keyboard Maestro operates. However, the utility might run a bit slower when using the main menu of the tool. Other than that, nothing bad can be said about this program as it does exactly what's being said on its homepage.
In conclusion, I think it's worth giving this utility a try if you want to complete tasks faster on your Mac.
