These are scripts that I use with FastScripts to extend functionality in Mac OS X applications.
I'm writing a series of blogs about them. This is what I've got so far:
- Finder/Copy Paths to Selected Items
 - iTunes/Copy Paths to Selected Tracks
 - iTunes/Renumber Selected Tracks to Current Order
 - iTunes/Edit Track Names in TextMate
 - Open Application’s Scripting Dictionary
 - Mail/Copy URLs for Selected Messages
 
For a possibly more up-to-date list, see the fastscripts tag.
