Fast Delete for Mac

From Avaritia Design:

Fast Delete is an AppleScript that will automatically move a file to the trash and delete it. Apply Fast Delete to a function key, and choose your trash! It's much quicker than selecting what you want to delete, then typing command-delete, waiting for it to move to the trash, and then typing command-shift-delete. It's so lengthy compared to the automation that Fast Delete gives you.
If you want extra-fast file deletion, assign Fast Delete to a function key and turn off the Trash's "Warn before emptying" option.
And make sure that you have the Akua Sweets Scripting Addition, or Fast Delete will not work.
