'Seeker', and 'Wanocaps'

Seeker

Seeker is an ultra-fast file search engine with search and replace functionality. Seeker not only searches for files (and even inside of files), it also lets you replace text inside of files. Regular expression support and command line parameter support makes Seeker a complete search and replace solution. All results from Seeker can be viewed in one of four advanced reporting modes, including: detailed file list, structured report, summary report, and summary report with file list. Don't miss out on the top Search and Replace application around!

Wanocaps

Most people seldom use the caps lock key on purpose; in fact, most accidentally pushed the key at least a thousand times. Now you can use Wanocaps -- the caps lock terminator! It’s not really a program, it’s actually a registry adjustment.
