I need to re-find a program that I had found online about a month ago.
 I want to try it out again but can no longer find it.  The program
allowed you to essentially set up a "shortcut" that would go to a
specified website, fill in a specified field with the given value, and
give the results.  For example, I could set it up so that I could
simply type "spell california" and it would, automatically, go to
dictionary.com, and fill in the appropriate field with the value
"california", giving me the definition.

The program could have been a toolbar or firefox extension but I
cannot remember for sure.  It is different than your typical form
filling program like google's autofill because you specify what value
to use at the time of use (not predefined values already stored by the
program).

What program am I looking for and where can I find it?

Thank you for the help!
