Rotating Control Stick

[starvingtodeath]

Hi, I'm currently playing Paper Mario TTYD and I'm at the part in Chapter 3 where you are given a new hammer. In order to use the new hammer's special ability, you have to hold B and rotate your control stick. This is a huge problem for me because I don't have a controller. Is there anyway to do this with a keyboard? I tried pushing up, left, down, then right repetitively but that doesn't seem to be working, probably because I'm not fast enough. Maybe there would be a way to setup a macro that simulates rotating a control stick?

I apologize if this is in the wrong forum section.

Rapidly press the arrow keys in circle (Do it real fast, be sure to press the next key before letting go of the old)

Am I out of luck if I'm not fast enough?
