Need a good "find Button Script"

[JacksHyperInfo]

I can create a find button that will respond with an ask dialog box -What are
you searching for- then I type in a word-It finds first occurence only. I
like to be able to hit the enter key or the return key and the dialog box
return with the word still present and search as many times as neccessary to
find all occurences of the word. I'm stumped-can some of you experienced
folks help me.
