Clever use of these tools by George Coghill, using Drafts to save text files quickly to Dropbox, Hazel to monitor the files for keywords and then execute AppleScript/Automator actions based on the contents of the file he saves.

I’d go one further and say that you could setup LaunchCenter Pro to add the text in Drafts for you, for your common triggers — thus automating this a bit more. Pretty clever, now I just need to decide what I want my iPhone to be able to tell my Mac.
