Classified Ad Spinner

I am looking for a piece of soft ware that will do the following:

Take spun text/html for ad title /ad text

Then use the function keys or something similar to paste the next spun text.

So I would select the text field for an ads title and hit F1 the program would spit out the next spun title and place it into the field
then the same thing with the ad body.

Would like to have more fields available to use ie F1, F2, F3, F4 each working the same way

This would allow for very fast manual classified submission to any classified site

So question is, does anything exist already that does this or something very similar?
If not would anyone here be able to program something to do this.

you could probably make a macro to do something like this. otherwise should be easy for someone to code something up.
