Since I found many useful workflows on this forum I decided to share a couple of simple workflows I made for my Alfred app.
This workflow simply toggles the Natural Scrolling of OS X. I like to enable the natural scrolling only when using my trackpad and disable it when using a mouse and keyboard.
Just type "ns" to toggle it ON/OFF. Download: http://goo.gl/1JhK33
I will post updates if there are any, feel free to post your suggestions and advices
