Noticed an Error in the Script as there was no exit routine so we are now at 1.2 (boy that was fast)

I included by default a number of modification instructions on which sections to comment out via the -- variable of applescript if you want it to run differently.

By Default the file is set to /Users/USERNAME/Desktop/Tags.txt

You can change it to whatever you want it to be, or simply pop up a dialog.

Also I removed the section of pasting it in to OmniFocus directly, as if you do not have any field selected it would put in a whole bunch of text in to it.

I will also Post another Script in a second to help with the searching, by using the same script just wording some things differently.
