Screen Sieve

Screen Sieve is a nifty tool for Mac OS X that lets you search the contents of the currently active window at any time. It highlights all occurrences of characters, words and phrases as you type, without requiring modifications to applications.

The “Command+F” works good to find things in a document or webpage, but there’s one thing I like about this app. “Screen Sieve doesn’t force you to change context. When you invoke the Find command, your window frequently ends up scrolling up or down. This makes you lose track of where you are. Screen Sieve simply highlights the visible matches, and ignores the rest until you decide to scroll further up or down.”
