Hi
If you're typing away in IRC or IM or Word or whatever and you want to just quickly grab the URL from the tab you were just looking at in Safari, this is the workflow for you.
https://www.dropbox.com/s/2q8xdry7am4xqvy/Paste%20current%20Safari%20URL.alfredworkflow
It's hotkey based, so you'll want to go in and define a hotkey.
There's also an alternate path which runs the URL through a shortener (tinyurl.com specifically).
This was heavily based on "URL to Clipboard" by Michael Matochkin. Thanks Michael!
Cheers,
Chris
