particle interaction?

I’m useing Blender v2.42 and I was takeing an online tutorial. The tutorial got to a point that tells me to press ‘F7’ and go to ‘particle interaction’. Well, I don’t have ‘particle interaction’ under ‘F7’

The tutorial was written for an earlier version of blender, so I’m guessing that it just has been moved. Can someone tell me were I can find ‘particle interaction’ in Blender v2.42


Press [F7] a second time to access the
sub-category Physics section.

There you’ll find a ‘Fields and Deflection’
panel which contains the options that
correlate to the features that you’re looking

(Also, it’s a good idea to post the link for
the tutorial you’re referring to).
