Finding Applications

This morning I wanted to send someone a screenshot of a long web page. I didn't want the printed goofiness of printing to pdf. I knew there was an app it tried out before and I could find the png I made with a long web page with it. However, I coulnd't remember it's name. How can I know the function of each of the 150 or so applications in my computer? Answer: Google Search: "mac os x" png screenshot september

It this just an "Adolph is crazy" question, or do other people have this problem? I want to be able to query the executables on my computer and ask: who does what? who can do this? who does the same thing? who takes the least resources to product the same product?
