'gd' doesn't do anything for me (recommended here: http://jmcpherson.org/editing.html )

The asterisk works great though!

• Read the string under the cursor and go to the next place it appears. (For instance, if your cursor was somewhere on the word "bob," the cursor would move to the next occurance of "bob" in your file.)

Same as above, except it moves the cursor to the previous occurrence.
