Text Bucket is a background application that stores those frequently used snippets of text that we all have hanging around. Email addresses, form mail responses, snippets of code, or Facebook statuses - they all go in here.
Instead of cluttering up your desktop or hunting around for things as you need them, Text Bucket keeps them all in one place.
Bring it to the foreground with a hotkey combination, choose the item you want to paste in (at most 2 keypresses will do it!) and it blinks away and inserts it for you. Your hands never need to leave the keyboard! Grab what you need fast, and it'll get out of your way so you can get back to work.
Plus, the snippets are customizable. Need to frequently post almost-the-same-thing? Store it in Text Bucket with macros to prompt you for the values you need this time around.
Want even more functionality? Slots can execute command line scripts, so you can process your output through Perl, Python, Applescript, or whatever else you choose.
